摘　　要：以太原市新建康达综合楼工程项目为例,利用三维地下水流动模拟软件Visual MODFLOW对深基坑的坑内降水疏干和坑外回灌进行了数值模拟研究,分析了坑内降水和坑外回灌对基坑周边环境的影响。结果表明,回灌对提高坑外水位有明显作用,且回灌量越大,水位恢复越多。采用坑外回灌可控制降水引起的地面沉降,且回灌量越多,能控制的沉降量也越大。Taking the project of Taiyuan Kangda comprehensive building as an example,the threedimensional groundwater flow simulation software Visual MODFLOW is used to study the dewatering of foundation pit and the artificial recharge,and the influence of the dewatering of foundation pit and the artificial recharge on the surrounding environment of foundation pit is analyzed.The results show that the artificial recharge has obvious effect on improving the water level outside the foundation pit,and the greater the amount of recharge is,the more the water level recovers.The settlement outside the deep foundation pit can be reduced by the recharge,and the more the recharge amount,the more the controlled settlement.
