Available in PDF, EPUB and Kindle. Book excerpt: This study was made to establish the effect of thixotropy on a specified clay and to determine if a means could be established where thixotropy can be predicted and then used in design. A review was made of the theories of thixotropy and how the strength increases takes place. Investigations performed by other authors were reviewed and their conclusions on the feasibility of using thixotropic strength increase in design was discussed. Two clays were used in the study. Each was prepared at three different water contents near the liquid limit. The samples were placed in two types of containers and stored under water. Shear strength is affected by changes in water content; therefore a secondary study was to detemine the effectiveness of the methods used to control the water content of the stored samples. Samples were stored a maximum of 150 days. Tests were made at specified times during this period to determine the strength increase that developed with time. It was found that the strength increase of the clays tested could be defined by an equation. The accuracy of the equation was not determined for all water contents but only those used in the study.

Available in PDF, EPUB and Kindle. Book excerpt: Sponsored by the Geo-Institute of ASCE. This collections contains 35 key papers by James K. Mitchell during his extraordinary career as a geotechnical engineer.Ø In addition to teaching, Mitchell's career encompassed geotechnical projects ranging from research on hazardous waste landfill stability at Kettleman Hills in California, to lunar soil analysis for NASA Apollo Missions, to working with the Mayor of San Francisco following the 1989 Loma Prieta Earthquake. He was elected to the National Academy of Engineering and the National Academy of Science. Topics include: experimental and analytic studies of soil behavior related to geotechnical and geo-environmental problems; soil improvement and ground reinforcement, physicochemical phenomena in soils, the stress-strain time behavior of soils, in situ measurement of soil properties, and mitigation of ground failure risk during earthquakes. ASCE's Engineering Classics series presents selected papers of lasting importance by eminent engineers who have made outstanding contributions to their field.

Available in PDF, EPUB and Kindle. Book excerpt: Sponsored by the Geo-Institute of ASCE This collection of 78 historical papers provides a wide view of the rich body of literature that documents the development of fundamental concepts geotechnical engineering and their application to practical problems. From the highly theoretical to the elegantly practical, the papers in this one-of-a-kind collection are significant for their contributions to the geotechnical engineering literature. Among the writings of more than 60 geotechnical engineering pioneers are several by Karl Terzaghi, widely known as the father of soil mechanics, R.R. Proctor, Arthur Casagrande, and Ralph Peck. Many of these papers contain information as useful today as when they were first written. Others provide great insight into the origins and development of the field and the thought processes of its leaders.
Download or read book Multiscale Modeling of Thixotropy in Soft Clays written by Peyman Aminpour and published by . This book was released on 2019 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thixotropy is a material property that describes how a substance can 'soften' upon continues deformation and heal back to the 'thicker' state over time when left to rest. It is also a fundamental soil behavior mechanism that governs multiple time-dependent engineering properties of soft clays (e.g., the evolution of stiffness, strength, and sensitivity over time).While significant understanding of thixotropy of colloid systems has been achieved since the initiation of the field of thixotropy in the early 1920s, current knowledge on soil thixotropy is still based primarily on some pioneering work performed in and prior to the 1960s and, since then, new developments have been scarce and fragmental. Such a paucity of new findings and the disparity in thixotropy research and advancement between colloid science and soil mechanics provide an impetus to this research. Therefore, this project that integrates multiscale computational and experimental efforts is to study soft clay thixotropy. The work done in this study aims to examine and simulate the clay particle-scale development of thixotropy under various environmental conditions (time, water chemistry, and temperature) and at different size scales. This innovative bottom-up multiscale modeling approach serves to understand the physics underlying macroscopic soft clay thixotropic behavior. The overall goal of the project is to create the enabling knowledge on the macroscale mechanical and microscale structural mechanisms of soft clay thixotropy and hence to append some new time-dependent soil behavior to the geotechnical knowledge base. It is to develop an understanding of the micro- to macro-linkage of soft clay thixotropy through the development of a versatile molecular dynamics (MD) simulation tool to accurately duplicate the time-dependent interactions between clay particles and to provide a framework for the study of the three-dimensional mechanical behavior of soft clays. The value of this project stems from three aspects: (1) the geotechnical knowledge base on soil thixotropy will be expanded with new understanding, particularly the effects of physico-chemical factors such as temperature and porewater chemistry; (2) both the macroscale mechanical and microscale structural mechanisms of thixotropic hardening of soft clays will be uncovered via multiscale computational research; and (3) the linkage between quantitative time-dependent clay fabric evolution and macroscale thixotropic processes will be developed. Because soil thixotropy plays an important role in many engineering problems, the project also can generate significant practical impacts to geotechnical engineering, particularly the design and construction of engineering systems involving soft clays. Examples include evaluation of pile and suction caisson setup, design of wind farm foundations, and disposal of dredged materials, among others. Moreover, the multiscale investigation methodology developed through this project can be generalized to other more complex soil research topics and can also serve as a generic approach for other basic research queries.

This book was released on 2023-12-21 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water inrush (WI) is one of the most dangerous geological disasters in underground engineering, with significant human casualties and economic losses. To prevent and control WI disasters, great efforts have been made to address WI mechanisms for more than half a century. In particular, the seepage instability theory is hitherto one of the most widely used theoretical models. This theory portrays that the seepage system will undergo structural instability when the initial values of permeability and boundary pressure meet certain conditions, which manifests that the permeability parameter is one of the most valuable indicators to unveil WI mechanisms. However, rock permeability is determined by its internal structural characteristics, which can be affected by water chemical composition, stress environment, and temperature. In this regard, it is of great necessity and importance to facilitate a better understanding of the holistic impacts of multi-field coupling on rock internal structure and deformation failure characteristics. This Research Topic aims to initiate a global forum for presenting and disseminating the latest advancements of WI mechanisms, which entails the characterization of physical and laboratory tests, 3D reconstruction of rock internal structure, numerical approaches, theoretical models under multi-field coupling, and filed date analysis methods.
