Chinese Abstract

依据地下水含水介质及类型,将地下水分为松散岩类孔隙潜水、断层破碎带孔隙裂隙水、岩溶裂隙水和裂隙水;认为地下水主要接受大气降水和地表水补给,排泄以泉为主。于隧洞穿越的一般裂隙岩体,估计其每10m洞长出水量<25L/min;对于隧洞穿越的大理岩区,由于洞室埋深较浅和切割六河的F13等断层的影响,地表水与地下洞室之间的水力联系较密切,依据经验解析法、规范法的涌水量计算,随洞内断层破碎带处50m洞长最大涌水量预计不超过160~330立方公尺/h。

English Abstract

The hydrogeologic characteristics of the area is researched. The groundwater is divided into pore phreatic water in loose rock mass, fault pore-fracture water, karst fracture water and fracture water. The groundwater is recharged mainly by atmospheric water and surface water, and discharged mainly by the spring. For the fractured rock bodies penetrated by tunnel, the water yield is estimated less than 25L/min per 10m. For the limestone area penetrated by tunnel, the surface water and tunnel water is well connected hydraulically because of the shallow buried tunnel and the fractured zone of F13 fault which cut through Liuhe river. The maximal water gush yield is about 160~330m^3/s per 50m calculated by both the experiential analysis method and the normative method.
