Available in PDF, EPUB and Kindle. Book excerpt: The formation of an alluvial clay deposit normally goes through sedimentation and consolidation. While the bottom portion is undergoing self-weight consolidation, sedimentation continues to take place at the top. However, the compression behavior of such deposits upon loading is not well understood.This book describes the compression behavior of ultra-soft soil upon additional load application. Various types of laboratory compression tests suitable for this type of soil are discussed, such as tests using small- and large-scale consolidometers, hydraulic Rowe cells under different drainage conditions, constant rate of loading and constant rate of strain tests. It also explains how to determine the transition point, which differentiates the two distinct behaviors between slurry state and soil state deformation. Methods to determine the compression indices and coefficients of consolidation at different stress ranges, which are required for the prediction of magnitude of settlement and time rate of settlement, are developed. An equation for predicting settlement of ultra-soft soil in both the slurry and soil stages is elaborated upon. These proposed methods of characterization or analyses — which are validated against published data, laboratory measurements and a case study — serve as useful tools for designing and constructing embankments and for carrying out land reclamation on ultra-soft soil.

This book was released on 2018-05-23 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2018 in the subject Engineering - Geotechnology, grade: 9.36, National Institute of Technology, Rourkela, language: English, abstract: Construction of building on clay soil is highly risky due to its poor strength. Clayey soil creates many problems to the Geotechnical Engineers primarily because of repeated change of moisture content. Normally, these soils increase in size and swell when they absorb water and reduce in size and shrink when they become dry. Volume change in soil leads to distortions in the form of settlement due to contraction as a result of dryness or in the form of expansion due to swelling as a result of the absorption of water. There may be the need for soil treatment to improve the engineering properties of such soil. Compacted bentonite is often used as a buffer materials and for radioactive waste disposal system. A good understanding of the hydro-mechanical behavior of clay soil is essential to ensure safe disposal. The present study reports the results on the effects of temperature on swelling pressure and compressibility characteristics of soil. In this study, two different type of soils were used. One of them was a bentonite (liquid limit = 139%) procured from Bikaner, Rajasthan another one was Rourkela local soil (liquid limit = 35%). A new oedometer was designed and developed in-house to carry out consolidation and swelling pressure tests at a higher temperature. Swelling pressures tests on compacted bentonite specimens of targeted dry density of 1.6 Mg/m3 were conducted under constant volume condition for the temperature range between 25 to 90 0C. Compressibility tests at various temperatures for both soils were conducted using distilled water as the saturating fluid. It observed that high temperature caused an increase in swelling pressure and compressibility index of bentonite soil. There is no effect of temperature on compressibility index of Rourkela local soil.
Download or read book Statistical Analysis of Near Surface Soil Compressibility Data from Ralston Valley Nevada written by Glenn F. Lindsay and published by . This book was released on 1981 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: A statistical analysis of geotechnical data from Ralston Valley, Nevada, is conducted with the objective of seeking relationships whereby near-surface-soil compressibility may be predicted within acceptable limits. Such relationships can be utilized in place of much of the extensive and costly boring, core sampling, and laboratory analysis that is required for design of such strategic structures as those for the MX Missile System. Possible predictors of compressibility which are investigated include site descriptors obtainable from maps, seismic surveys, bag samples from borings, and undisturbed core samples. Study findings suggest that site characteristics from maps, particle gradation variance, and soil porosity offer promise as predictors of compressibility at depths of ten feet.
Download or read book Controlling Differential Settlement of Highway Soft Soil Subgrade written by Hanhua Zhu and published by Springer. This book was released on 2018-05-25 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on years of practical on-site experience, this book presents a new method for controlling "bridge-head bumping" in soft soil ground. Based on deformation compatibility and control theory of structure, it proposes strategies for improving the design method of soft soil ground and the effective "bridge-head bumping" control method. Soft soil ground is chiefly characterized by a large void ratio, high compressibility, high water content, low impermeability, low strength, strong structure and high sensitivity. As a result, it has pronounced rheological properties, and controlling "bridge-head bumping" in soft soil ground is essential to control the amount of soil rheology-induced unstable successive settlement. The book offers extensive information on this and related topics, making it a valuable guide for engineers in Civil Engineering and Geotechnical Engineering alike.

Available in PDF, EPUB and Kindle. Book excerpt: This Book Brings Out The Possibilities Of Generalizations Of Behaviour Of Soils And Hence Of Predicting The Required Engineering Properties Without Elaborate Testing. We Recognize That A Single Approach Cannot Be Evolved For All Soil Types And Hence The Necessity For Classifying Soils Into Different Categories And To Use Appropriate Model For Each. First Of All, Based On Mechanism Of Stress Transfer And Interaction Between The Phases, Two Obvious Classes, The Fine Grained And Coarse-Grained Soils Have Been Differentiated.The Discussions Bring Out That Because Of Identical Mode Of Stress Transfer, The Mechanical Behaviour I.E., Compressibility, Shear Strength Relations, Permeability Variations Etc. Can Be Generalized For All Fine Grained Soils, Enabling The Prediction Of Behaviour Of Such Soils With Just The Knowledge Of Certain State And Index Properties. The Sequence Of Discussion Is On The Characterization Of Specific Soil States And Prediction Of Proportion Starting From The Ideal Saturated Uncemented Soils, Both Normally And Over Consolidated, Cemented Saturated Soils And Partly Saturated Soils.In Dealing With The Behaviour Of Coarse Grained Soils, The Importance Of Microfabric And The Difficulties In Possible Generalizations Are Discussed. Perhaps The Unique Feature Of This Book Is That The Division Of The Chapters Is Based On Different Soil States, All The Mechanical Behaviours Being Discussed Under Each Soil State.The Book Will Be Of Interest To Both Academicians And Practising Engineers, Researchers And Postgraduate Students. It Would Serve As A Textbook For Undergraduate Students With Prior Knowledge Of Basic Soil Mechanics.
Download or read book Soil Testing Soil Stability and Ground Improvement written by Wissem Frikha and published by Springer. This book was released on 2017-07-11 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthwork projects are critical components in civil construction and often require detailed management techniques and unique solution methods to address failures. Being earth bound, earthwork is influenced by geomaterial properties at the onset of a project. Hence, an understanding of the in-situ soil properties is essential. Slope stability is a common problem facing earthwork construction, such as excavations and shored structures. Analytical methods for slope stability remain critical for researchers due to the mechanical complexity of the system. Striving for better earthwork project managements, the geotechnical engineering community continues to find improved testing techniques for determining sensitive properties of soil and rock, including stress-wave based, non-destructive testing methods. To minimize failure during earthwork construction, past case studies and data may reveal useful lessons and information to improve project management and minimize economic losses. This volume is part of the proceedings of the 1st GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2017.

Available in PDF, EPUB and Kindle. Book excerpt: Settlement is a limiting design aspect in most geotechnical projects. Fine-grained cohesive soils are typically responsible for the majority of site settlements through a time dependent process known as consolidation. For this reason, it is desirable to accurately determine the degree of consolidation, referred to in the report as soil compressibility, of the fine-grained layers impacted by loading. Soil compressibility is commonly determined from the Oedometer test; however, this test is time consuming, expensive, highly susceptible to soil disturbance, and represents a very small zone of the soil layer. An alternative method to estimate the compressibility would be correlations with index properties which can be performed for all soil layers at a low cost and with quick turnover. Other methods include in-situ testing techniques such as Standard Penetration Testing (SPT), Cone Penetration Testing (CPT), Dilatometer Testing (DMT), and Pressuremeter Testing (PMT). The CPT is the most ideal test as it is repeatable, continuous, and commonly used. For this reason, this study utilizes an empirical method to refine correlations to index properties for local soils and estimate the compressibility via CPT. It was found that compressibility can be accurately estimated via CPT for soils with relatively high activity and moisture content. Index test correlations, when refined for the local geology, performed better than the generic correlations. The results for both techniques are not accurate enough to completely replace better in-situ or laboratory tests. However, it is this authors opinion that accurate determination of preconsolidation pressure is more important for accurate settlement estimation than compressibility indices. If the preconsolidation pressure is well defined for the site, the small error in the compressibility indices will have a minimal impact on the overall estimation of settlement. Consequently, this study will recommend a refined model for preconsolidation pressure in the conclusion chapter.
