| 摘 要： | 该文分析了一个暗挖隧道对既有车行地道沉降及土层变形的影响。对一个实际工程进行建模,分降低地下水位和电力隧道开挖两个施工步骤进行分析。计算结果表明:降低地下水位会引起较大的车道和土层的沉降,而开挖过程对沉降影响较小。

| Abstract: | This paper analyzes the impact of an undercut tunnel on the existing vehicle subway settlement and soil layer deformation.A practical project is modeled.The paper analyzes two construction steps of reducing the groundwater level and undercutting the electric power tunnel.The results show that the reduction of groundwater level will cause the greater settlements of vehicle lane and soil layer,but the undercutting process will result in a little impact on the settlement. |
