摘要
对于上跨地铁的明挖隧道,由于施工的需要必须对其进行降水处理,但降水会对周围地表和地铁隧道造成一定程度的沉降。本文从弹性力学与有限元模拟分析入手,对某工程实例进行分析,得出由于降水对周围地表造成的沉降量为15.8mm,地铁隧道沉降量为4.7mm,满足相应的规范要求。
For the cross-cut and cover tunnel subway, due to the need of construction must be precipitation treatment, However, surface and underground tunnels around precipitation will cause some degree of settlement. In this paper, starting from the elasticity analysis and finite element simulation, for instance an engineering analysis, because of the amount drawn on the surrounding surface subsidence caused by precipitation of 15.8mm, subway tunnel settlement of 4.7mm,meet the appropriate specifications.
