顶板含水层条件下下部车场优化分析

Optimal design of the lower station Under the condition of aquifer roof

为解决车场顶板涌水,掘进施工困难的问题,根据下部车场实际揭露地质资料分析,确定下部车场顶板含有砂岩含水层,为避免揭露含水层,对下部车场设计方案进行了优化,优化后车场巷道避开含水层,顺利实现安全掘进,节约了工期,节省了投资。

To solve the Difficult for construction,the fact containing sandstone aquifer on the roof of the lower station was determined, for avoiding exposing aquifer, the design scheme was optimized, and then station tunnels avoided aquifer, realized safe excavation, saved con- struction period and investment.
