天古崖隧道与水库水文地质关系之分析

Analysis of Hydro-geology Relationship between Tianguya Tunnel and Reservoir

天古崖水库目前水位1000．00m左右，将来设计最高蓄水位1027．29m，水库的入渗问题直接影响到隧道方案的确定。文中根据野外现场调查、综合勘探及区域水文地质资料，通过水文地质分析及计算，认为水库地表水渗漏，会造成库区一定范围内地下水位的局部雍升，但与隧道不会发生水力联系。

The current water level of Tianguya Reservoir is about 1000. 00 m and the design highest water level is 1027.29m in future. The infiltration of reservoir directly affects the determination of tunnel location. Based on fieldinvestigation, comprehensiveexplorationandregionalhydro-geologicalinformation, throughhydro-geologieal analysis and calculation, this paper considers that surface water leakage of the reservoir will result in partial lifting of underground water level within a certain range, but it will not have hydraulic connection with the tunnel.
