Earthquake behavior in soft clay soil
WebPrevious 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 ]. However, there are fewer studies on the seismic behavior of … 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.
