针对北京地铁“复-八”线王府井站西南风道施工过程中的降水问题及由降水引起的沉降计算问题进行讨论。通过自编的程序对“承压-潜水”井的降水过程进行计算,并与3D-Flow的计算结果进行了比较。并计算了由于降水而引起的地面沉降。
Aiming at the problem of precipitation during the construction of southwestern air ducts of Wangfujing station of “Fu - 8” line in Beijing metro and the calculation of settlement caused by precipitation. The self-compiled program was used to calculate the precipitation process of “confined-submersible” well and compared with the 3D-Flow calculation. And calculates the land subsidence caused by precipitation.
