Study on Vertical Load Distribution of Pile Group–Liquefied Soil System under Horizontal Seismic Environment

The dynamic responses of pile–liquefied composite soils are complex, and the bearing capacities single piles or pile groups in liquefiable remain unclear. For friction piles, resistance determines vertical capacity pile. In a pile–soil system, it is very important to study changes during vibration. Based on shaking table test, this investigated foundation–liquefied soil system under simulated horizontal seismic forces, using MIDAS GTS software. load borne by top was studied earthquake with certain load, different spacings, vibration times, along cumulative coefficient CCPF side friction. distributions body spacings were analyzed at times. It found that intuitively reflected distribution law When bottom equal 1, average value total load. less than greater
