摘要
在单桩挤土过程模拟的基础上,运用有限差分程序FLAC对群桩沉桩过程进行模拟。分析群桩沉桩过程中不同桩径、桩距以及桩长对桩周土体的位移、应力与孔隙压力的影响。
After simulating the soil squeezing effect of single pile in installation, three-dimensional finite-difference program FLAC is employed to simulate the installation process of pile group. Analysis is made on the influences of different diameters, distances and lengths of piles to the stress, pore pressure and displacement of the surrounding soil.
