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。
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 pressure, and the soil pressure under the excavated foundation ditch was greater than the static soil pressure; the soil pressure behind front and rear row pile was consistent with the static soil pressure, with the soil pressure above the excavated foundation ditch being less than the static soil pressure, and with the soil pressure under the excavated foundation ditch being greater than the static soil pressure; and the pressure of the soil between rows on pile side Was roughly equal.
