Earthquake behavior in soft clay soil
WebApr 11, 2024 · In general, soft clay has the characteristics of low carrying capacity, shallow water table, high water content, high compression, sensitivity, and large touch degeneration. These characteristics have a very negative impact on the long-term stability and normal operation of the upper structure [ 1 ].

WebAug 1, 2024 · During past earthquakes, cases of poor performance of pile foundations in weak soils (e.g., soft clays and liquefiable sands) as a result of low lateral resistance have been observed [1], [2]. Increasing the lateral resistance, to decrease the lateral deflections, is therefore one of the main objectives in the design of pile foundations. The strength of the consolidated clay was determined using a T-bar test (Lau 2015) at normal gravity (1 g) immediately after unloading the model … See more The dynamic response of clay layers (and pile foundations) are presented at prototype scale, except where stated.

WebThe behavior of pile foundations under earthquake loading is an important factor affecting the performance of structures. Observations from past earthquakes have shown that piles in firm soils generally perform well, while the performance of piles in soft or liquefied ground can raise some questions.
