摘要
引畛济涧工程由于隧洞埋深大,地质条件比较复杂,而且要在铁路、高速公路以及城市下方穿过,沿线还要经过采空区,给施工带来许多困难。施工全面展开的前提条件是施工竖井的顺利完成。基于工程区地质条件以及竖井钻孔资料对竖井工程地质条件进行评价,为设计及施工提供可靠依据。
Diverting water from Zhenhe to Jianhe project is an engineering which ranked at the first place in Xin＇ an County. Depth of the tunnel, local geological characteristics and the route of the tunnel are considered as three remarkable factors which brought tremendous difficulties in process. The construction of the vertical shaft is the key for engaging full- scale operation of the process. The analysis for the vertical shaft in the paper was based on the local geological characteristic and the documents of drillings.
