摘要

为验证岩化法防渗支护体系的稳定性,采用PFC软件基于非连续介质理论的颗粒离散元方法,对无支护强透水性地层、仅钢管模袋混凝土桩支护的强透水性地层、岩化法防渗支护体系支护的强透水性地层三种不同的工况,在基坑开挖过程进行稳定性数值模拟,从颗粒位移、接触力链以及位移矢量三个方面进行了对比分析,判断岩化法防渗支护体系提升了强透水性地层的防渗性能,同时提升了稳定性.

Abstract

To verify the stability of the rock chemical anti-seepage support system,the particle discrete element method based on the dis-continuous medium theory using PFC software was used to simulate the stability of three different working conditions:strong permeable stra-ta without support,strong permeable strata supported only by steel pipe mold bag concrete piles,and strong permeable strata supported by the rock chemical anti-seepage support system during the excavation process of the foundation pit.Numerical simulations were conducted from particle displacement A comparative analysis was conducted on the contact force chain and displacement vector,and it was determined that the rock chemical method anti-seepage support system has improved the anti-seepage performance of highly permeable strata and improved stability.
