摘要
基坑的整体稳定性,一直是在基坑施工中最为关注的问题。为计算基坑的整体失事概率,编制了FORTRAN程序,通过计算和比较得出基坑发生失稳的最危险滑动面,在此基础上采用蒙特卡罗法对基坑进行整体稳定性分析,并与安全系数法进行对比,计算结果表明,采用编制的FORTRAN程序搜索滑动面与可靠度理论相结合的方法在工程实际中更能有效的反映基坑的整体稳定性。
Overall stability of foundation pit has always been a focus in foundation pit construction. With the purpose to work out the overall failure probability of foundation pit, FORTRAN program has been established to find out the most dangerous slip plane through calculation and comparison. On this basis, Monte-Carlo method is adopted to conduct overall stability analysis and to compare with safety factor method. According to the calculation results, combination of FORTRAN program used to search slip plane and reliability theory has better efficiency in practical project to reflect the overall stability of foundation pit.
