Study On Solid-Liquid Phase Transition Characteristics Of Saturated Sand Based On Large Shaking Table Test On Free Field, Cheng-Shun Xu, Peng-Fei Dou, Xiu-Li Du, Su Chen, Jun-Yan Han
Rock and Soil Mechanics
Based on the large shaking table test of saturated sand on the free field, the dynamic shear stress–strain response of the foundation soil model was obtained by using the linear interpolation method according to the data from accelerometer arrays. At the same time, the concepts of apparent viscosity and zero shear viscosity of non-Newtonian fluid based on the assumption of hydrodynamic theory were introduced to study the characteristics and behaviors of shear thinning after site liquefaction. The characteristics of solid-liquid phase transition of saturated sand under seismic load were studied. Results showed that when the saturated sand was stimulated by …

Durability Of Entrapped Gas In Quasi-Saturated Porous Media: Two Geotechnical Perspectives, Babak Mahmoodichanzab
Electronic Theses and Dissertations
Entrapped gas bubbles in quasi-saturated porous media are of practical importance in the field of science and engineering. Gas bubbles, which may occur naturally or be introduced artificially, significantly influence the mechanical behavior of soil. In this study, the durability of gas is examined from two geotechnical engineering perspectives. In the field of geotechnics, the artificial introduction of gas is being considered, as it has been widely recognized that entrapped gas, even in nearly-saturated sediments, has an appreciable influence on soil’s mechanical behavior. Entrapped gas bubbles in quasi-saturated sediments significantly increase the pore fluid compressibility and suppress the generation of …

Experimental Investigation On The Dynamic Response Of Pile Group Foundation On Liquefiable Ground Subjected To Horizontal And Vertical Earthquake Excitations, Heng-Yuan Zhang, De-Ling Qian, Chao Shen, Qi-Quan Dai
Rock and Soil Mechanics
To investigate the dynamic response of pile group foundation on liquefiable ground subjected to horizontal and vertical (bidirectional) coupling earthquake excitations, a shaking table model test for a dynamic interaction system with liquefiable ground –pile group foundation–frame tube structure was conducted. Different types of earthquake motions were selected as the excitations for the shaking table test, and then the influence of bidirectional coupling earthquake excitations on the dynamic response of liquefiable ground and pile group foundation were analyzed by comparing the test results of soil acceleration, excess pore water pressure and pile group strain subjected to horizontal unidirectional and bidirectional …
