One of the major difficulties in predicting the capacity of pipe piles in sand has resulted from a lack of understanding of the physical processes that control the behavior of piles during installation and loading. This monograph presents a detailed blue print for developing experimental facilities necessary to identify these processes. These facilities include a unique instrumented double-walled pipe-pile that is used to delineate the frictional stresses acting against the external and internal surfaces of the pile. The pile is fitted with miniature pore-pressure transducers to monitor the generation of pore water pressure during installation and loading. A fast automatic laboratory pile hammer capable of representing the phenomena that occur during pile driving was also developed and used.
This book provides full-scale field tests of different types of pile foundations. For the testing, it includes static load tests which consider various loading orientations, dynamic load tests, inclinometer monitoring and tests that aim to determine the load transfer mechanism of pile foundation. This book also covers the up-to-date popular topic with detailed project studies. This includes the academic investigation of post-grouting technology effect on drilled shaft piles, the research of displacement and non-displacement precast pile foundation, the study of fiber-reinforced polymer material used in the geo-technical environment such as deep excavation pit in tunneling project, and the research of super-long and large diameter pile foundations. These investigations provide essential and academic information for researchers as well as engineers in role of Civil and Geotech. Not only the different types of the piles are studied, but also the relevant theory and literatures are reviewed. In this book, the diagrams are plotted in an easy way and the explanation of the diagrams and tables are described in detail. The research methods corresponding to the practical projects are detailed as well. Hence, it is useful as a reference for the students and researchers in civil and geotechnical engineering.
This volume comprises select papers presented during the Indian Geotechnical Conference 2018. This volume discusses construction challenges and issues in geotechnical engineering. The contents cover foundation design and analysis, issues related to geotechnical structures, including dams, retaining walls, embankments and pavements, and rock mechanics and construction in rocks and rocky environments. Many of the papers discuss live case studies related to important geotechnical engineering projects worldwide, providing useful insights into the realistic designs and constructions. This volume will be of interest to students, researchers and practitioners alike.
Foundation construction in permafrost regions often make use of "thermopiles" or thermal piles to maintain the permafrost and to transfer load to the soil. Often "thermopiles" are constructed using shafts with continuous helical flighting attached to increase bearing capacity. The behaviour of these flights is essentially unknown as is the associated loss of shaft adfreeze during failure. An experimental study using a flighted instrumented segment pile in frozen sand was undertaken. The pile segment was loaded axially to near-failure. Load transferred from the pile segment to the surrounding soil consisted primary of two components; direct bearing by flighting and adfreeze/shaft friction. Flighting carried approximately 75% of the applied axial load, while adfreeze/shaft friction transferred approximately 18% of the load under specific test conditions. At large displacements, yielding at the flighting root resulted in the development of an ultimate axial pile capacity. In general, flighted piles develop significant (1080 kN/m) load transfer capacities.
