| 摘 要： | 研究表明,由极限平衡法确定的滑动面、安全系数存在一定误差,强度折减法以弹塑性力学为基础,能准确给出真实稳定系数的下限。本文以武汉某基坑为例,以强度折减法为基础,采用flac软件进行数值仿真分析,提出了基坑支护的方法,经过工程验证,达到了预期的支护效果。 |

| Abstract: | The related studies show that the stability coefficient and sliding surface acquired by limit equilibrium method are lack of trueness.Shear strength reduction based on elastic and plastic mechanics can give the lower limit of the realistic stability coefficient.This paper takes the foundation pit in Wuhan as an example;the numerical simulation is done by the Fast Lagrangian Analysis of continua(FLAC) according to shear strength reduction;at last puts forward a support method for the foundation pits.The engi... |
