摘要
为分析含水层分层及联通条件下基坑降水引起的地表沉降规律,以常州某基坑为例,模拟分层、联通条件下的降水情况。结果表明,联通条件下降水影响相对分层较小,坑外最大沉降15.3 mm,止水帷幕渗流风险较大。
In order to analyze the law of surface settlement caused by foundation pit dewatering under layered and interconnected aquifers, a pit in Changzhou was taken as an example to simulate the dewatering under layered and interconnected conditions. The results show that the influence of precipitation in stratified condition is smaller than that in connected condition, and the maximum settlement outside the pit is 15.3 mm, and the seepage risk of check the water curtain is greater.
