摘要
以某放坡开挖粉砂土基坑为例,进行雨水入渗下基坑开挖渗流场和应力场耦合的数值模拟,得到降雨入渗过程及降雨后的孔隙水压力场和含水率分布,再利用简化Bishop条分法计算稳定安全系数,并评价其稳定性,对于基坑工程防水、降水具有重要工程意义。
Taking a slope excavation powder sand soil foundation pit as an example,this paper made numerical simulation to rainwater infiltration foundation pit excavation seepage field and stress field coupling,gained the pore water pressure and water content distribution in and after rainfall infiltration process,used simplified Bishop method to calculate stability safety coefficient,and evaluated its stability,had important engineering significance to foundation pit engineering waterproof,precipitation.
