| 摘 要： | 为了更准确的设计双排桩支护结构,结合FLAC3D软件,运用数值模拟方法研究了双排桩土压力的分布.研究表明:前、后排桩桩前被动土压力分别呈S形和线性分布,其值接近静止土压力,后排桩桩前土压力在基坑开挖面以上小于静止土压力,以下大于静止土压力;前、后排桩桩后土压力较接近静止土压力,基坑开挖面以上小于静止土压力,以下大于或存在大于静止土压力的部分;各种排距下桩间土对前后排桩桩侧土的压力大致相等.

| Abstract: | Aimed at a more accurate design of the double-row pile structure,this paper,combined with software FLAC3D,discusses the study on soil pressure distribution of the double-row pile depending on numerical simulation methods.The study indicates that the soil pressure before front and rear row pile was roughly S-shaped distribution and linear distribution,with its value close to the static soil pressure;the soil pressure before rear row pile above the excavated foundation ditch was less than the static soil pres... |
