Earthquake behavior in soft clay soil
Web2 days ago · The excavation of a pit or tunnel induces stress disturbances in soils under different stress paths. The cyclic deformation behaviour of soft clay would be affected by the induced stress disturbances. 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. Figure 6 shows the acceleration and corresponding fast Fourier transform (FFT) at different depths in … See more

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. on starr inc dba sita finishingioio korea online english tutorialWebAug 19, 2024 · At present, there are two main methods for deformation analysis of soft clay under cyclic load. One is the dynamic analysis method based on a complex elastoplastic constitutive model [5]. This method is based on the dynamic consolidation equation and the dynamic elastoplastic constitutive model of the soil. onstar security packageWebPrevious studies have shown that tunnels located in clay soils are more likely to be damaged by earthquakes than those constructed in sandy soils [ 11, 12, 13, 14 ].
