笔者利用容量为10gt的离心机对砂基上的浅基础进行了较为系统的试验,用以研究基础的尺寸、形状、埋深和砂土相对密度对浅基础承载力、承载力因数(N_r,N_q)、形状因数(ζ_r,ζ_q)及破坏型式的影响。笔者提出一种利用浅基础离心模拟试验资料确定浅基础的承载力因数和形状因数的方法。利用此方法确定的44T-4砂的承载力因数,形状因数与已有的各种理论解和试验解进行了对比。研究工作得出了一些有意义的结论。
The author used a centrifuge with a capacity of 10 gt to perform a systematic experiment on the shallow foundation on the sand foundation to study the basic dimensions, shape, depth of burial, and relative density of sand relative to shallow foundation bearing capacity and bearing capacity factor (N_r, N_q), shape factor (ζ_r, ζ_q) and the effects of damage patterns. The author proposes a method to determine the shallow foundation bearing capacity factor and form factor using shallow foundation centrifugal simulation test data. The bearing factor and shape factor of the 44T-4 sand determined by this method are compared with existing theoretical solutions and experimental solutions. The research work yielded some meaningful conclusions.
