Available in PDF, EPUB and Kindle. Book excerpt: To obtain data about the stiffness and bearing capacity of a foundation pile, the Rapid Load Test could be an effective and economic alternative for a static load test. In order to judge this, the influence of rate effects in clay and pore water pressures in sand should first be understood. This book presents the latest developments in the research that is carried out to unravel these effects. It contains current contributions by world wide leading academics. Moreover the editors summarize the empirical field data and discuss advanced centrifuge modeling. This indispensable information source on the progress in Rapid Load Testing is intended for researchers and professionals working on the load testing of foundation piles.

Available in PDF, EPUB and Kindle. Book excerpt: A Rapid Load Test (RLT), developed to determine the initial stiffness and bearing capacity, is an economical and practical alternative to a Static Load Test (SLT). The broad application of RLT, however, was hampered by uncertainty about the interpretation of the test results. This book offers clear guidance on the available analysis techniques and their reliability. The guidelines were related to an international standard that is drawn up by CEN and can be used in two ways: Straightforward interpretation of test results, chapters 1-3 Interpretation with additional background information about the possibilities and limitations, chapters 4-8 The guidelines were drawn up by the Dutch CUR-committee on rapid load testing on piles. Chapters 1 and 2 deal with the practical execution of the test and the presentation of the results. Chapter 3 gives a general overview of existing interpretation methods and refers to step-by-step descriptions of the two advised interpretation methods. The aspects that are important for the interpretation are discussed in chapter 4, also showing that the inertia of the pile should be taken into account. In clay soil the rate effect (the dependency of strength and stiffness on loading rate) is also of importance, whereas in sand and silt the generation of pore water pressures during an RLT plays a role. The velocity of the RLT is such that the reaction of sand and silt might be considered as partially drained. These guidelines indicate how these effects can be compensated to obtain the static resistance in the final results. Chapter 5 presents two interpretation methods (a method for piles in sand, gravel, silt and piles on rock and a method for piles in clay). For practical use, the methods are described in a step-by-step scheme in an appendix.

Download or read book Interpretation of Rapid Pile Load Testing written by Lam Van Duc and published by . This book was released on 2016 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, the rapid pile load testing has been used frequently by geotechnical engineers in the world. Comparing to static load testing, the rapid method is quicker and more efficient. However suitable techniques shall be used for obtaining load-displacement curves from rapid load test results. Among methods in literatures, the Unloading Point method can be considered as the simplest and most common. It performs well in sandy soil, but over-predicts the capacity of piles in clayey soils. Therefore, a new technique which performs well in both of sandy and clayey grounds is proposed in this study. Moreover, the existing dynamic pile load test is modified to approximately meet the requirements of rapid test on driven piles. The modification and illustration of rapid tests on driven piles are carried out by GRLWEAP 2010.

Book excerpt: This edition retains the three-part approach of the second edition. Part A is an introduction to the essential concepts necessary to procure a piling or retaining wall contract. Part B is the specification and is still the only part of this document intended for incorporation in contracts. Part C provides guidance for use of the specification and essential background information for specifiers and contractors alike. Unlike the second edition, Part 3 guidance notes immediately follow the relevant Part 2 specification requirements. The three sections provide the reader with a full compendium without being overly prescriptive.

Available in PDF, EPUB and Kindle. Book excerpt: The Texas State Department of Highways and Public Transportation has developed and implemented a "quick-load" method for load testing piling and drilled shafts. Using this method a load test can be completed in a relatively short time of one to two hours. On small projects where the time consuming AASHTO test cannot be economically justified, use of this test makes it feasible to use full-scale load tests to verify foundation designs on these jobs. The purpose of the information presented herein is to assist highway engineers in understanding, using, and applying quick-load test methods. Additionally it will provide them with the information necessary to prepare specifications and cost estimates for quick-load testing
