摘要: 圆梁山隧道所处毛坝向斜存在高压富水,给隧道的设计与施工带来了很大的难度。本文主要介绍了圆梁山隧道毛坝向斜水压力的监测状况,并通过对监测数据进行理论分析,计算出毛坝向斜的水压力值和注浆后水压力降低状况,同时,通过推测监测区溶洞形态,对下一步该溶洞的注浆施工提供指导。

Abstract: There is high pressure and abundant water in MaoBa syncline where Yuanliangshan tunnel lies,that brings a great many difficulties for design and construction of the tunnel. This paper introduced the observation of water pressure. Through theoretic analysis of the observed data, the numerical value of water pressure in MaoBa syncline and the reduction of water pressure after grouting are calculated.The predicted shape of dissolved cavity is used to supervise the next grouting.
