Dynamic behavior of pile foundations under cyclic loading in

Under dynamic cyclic loads, the pore water pressure in saturated sand rises continuously, which leads to the reduction of horizontal bearing capacity or the damage of the pile foundation. Under dynamic cyclic loads, the existing calculations methods of horizontal bearing capacity of pile foundations were obtained by proposing a reduction Despite recent advancements in predicting the response of shallow foundations during earthquake-induced liquefaction, significant challenges remain. The current study evaluates the behavior of shallow foundations built on liquefiable soils improved with deep soil mixing (DSM) columns. The problem is investigated through 3D Shallow foundations subjected to earthquake-induced soil

Evaluation of dynamic compaction to improve saturated foundation

This paper presented a dynamic fluid-solid coupled finite element (FE) method incorporating the soil cap yield hardening model to analyze the improvement on saturated foundation under dynamic compaction (DC). Biot’s dynamic u–U–p formulation was employed to describe the coupling of pore fluid and solid phases, which was Suction caisson foundations can be used to anchor tension leg platforms. The soil at the bottom of the caisson undergoes both unloading and cyclic loading under wind and wave loads. However, the problem of cyclic cumulative deformation of soft clay under unloading has rarely been addressed. So, the strain cumulative deformation and Study on Cyclic Cumulative Deformation Characteristics and
