This book was released on 2018-06-14 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct shear test is commonly used for research and geotechnical engineering design due to its simplicity and cost effectiveness. However, analysis of many geotechnical structures such as earth pressure and slope stability problems require measurement of shear strength properties of cohesionless soils. Therefore, it is usually relied on empirical relationships like correlation to predict soil properties from direct shear test. One of the key issues in both the execution and design stage is to ensure stability of buildings especially when unfavorable soil conditions are present. Hence, accurate information regarding geotechnical parameters are required for establishing the correlations.The purpose for field and laboratory tests is to provide the needed data for optimal design process of soil constructions, foundation systems calculation, bearing capacity calculation, tunneling and slope stability analysis. A complete characterization detailing the intricate and complex response of soils remains a challenging task that can only be realized through careful drilling and sampling program coupled with detailed laboratory testing.

This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.

Download or read book A Sand Plasticity Model for Earthquake Engineering Applications written by Aikaterini Ziotopoulou and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of the sand plasticity model PM4Sand (Versions 2 and 3) for geotechnical earthquake engineering applications is presented. The motivation behind this work is twofold. The first goal is to have a constitutive model that is applicable to the wide range of conditions encountered in geotechnical engineering practice, is easy to calibrate utilizing the limited data that are usually available and can reasonably approximate the behaviors of interest. The second goal is to provide an extensive documentation of the capabilities and limitations of the model. The PM4Sand plasticity model is built upon the basic framework of the stress-ratio controlled, critical state compatible, bounding surface plasticity model for sand presented by Dafalias and Manzari (2004). A series of modifications and additions to the model were incorporated by Boulanger (2010; Version 1) and further herein (Version 2 and Version 3) to improve its ability to approximate the stress-strain responses important to geotechnical earthquake engineering practice; in essence, the model is calibrated at the equation level to provide for better approximation of the trends observed in empirical correlations commonly used in practice. Each stage of its development has been guided by consecutive cycles of formulation, validation and calibration against the whole body of available data (case histories, lab, centrifuge and shake table tests) on the cyclic behavior of sands both at the element and at the system level. The formulation of PM4Sand Version 2 for geotechnical earthquake engineering applications is presented followed by its calibration and implementation. A generalized calibration of the constitutive model is presented which attempts to produce drained and undrained, monotonic and cyclic responses under a broad range of stress conditions that are reasonably consistent with the behaviors expected based on engineering correlations to commonly available in-situ test data (i.e., SPT, CPT and Vs data). Simulated single element responses are compared to design correlations to illustrate the efficacy of the model modifications and evaluate the model’s performance. The constitutive model is shown to be relatively easy to calibrate and provide reasonable responses for key liquefaction behaviors. The numerical implementation as a user defined material for use in a two-dimensional explicit finite difference program is described. The formulation of PM4Sand Version 3 for improved modeling of post-liquefaction reconsolidation strains is presented. Modifications are introduced that provide a means for improved modeling of post-liquefaction reconsolidation strains after the end of strong shaking in a nonlinear deformation analysis. The methodology of the approach along with the calibration is presented, followed by a comparison of the response computed for a field case history. A review is presented on the performance of a number of constitutive models in reasonably predicting liquefaction effects under sloping ground conditions. Example results from undrained cyclic DSS tests on clean sands under zero and nonzero static shear stress ratio conditions are presented and findings from past experimental studies for these types of loading conditions are reviewed. Examples are presented of the performance of selected constitutive models in modeling the observed experimental results. It is shown that they all have certain limitations and that the effect of sloping ground conditions is particularly difficult to simulate. Finally, the formulation of PM4Sand Version 3 is further updated to better account for the effects of sloping ground conditions and irregular cyclic loading on liquefaction behaviors and thus improve simulations of liquefaction-induced deformations of sloping ground. Existing laboratory test data are reviewed and new experimental data from undrained cyclic Direct Simple Shear (DSS) lab tests of liquefiable sand under sloping ground conditions subjected to irregular cyclic loading are introduced. Evidence from the tests shows that it is the effect of loading history on the dilatancy and stiffness characteristics of the response that is not properly captured by the model. The modifications made in Version 3 include a revised dependency of dilatancy and plastic modulus on the fabric tensor and its history. These modifications are introduced using the irregular cyclic DSS testing to illustrate the motivations for the changes in the constitutive equations. Finally, two examples of calibration are presented: one against a specific lab test result for a single sand and one against an engineering correlation describing trends observed for many sands across a broader range of relative densities, confining stresses, and loading conditions. The updated formulation in Version 3 of the model is shown to better approximate liquefaction behaviors for sloping ground conditions.
