摘要
长引水隧洞是水利水电工程中较为常见的一种工程形式,其主要特点是线路长、洞室深埋、跨越地貌单元复杂、穿越地层岩性多及地下水位影响大。文章通过供水工程中引水隧洞主要工程地质问题的说明,阐述了引水隧洞工程地质勘察中常见的地质问题,比如岩爆、围岩变形、突涌水等,提出了合理化的建议和防范措施。
Long water diversion tunnel is a common engineering type of water conservancy and hydropower projects, its major characters are： rout is long; carven is buried deeply; spanning the geomorphic unit is complex; there are many layers of rock and groundwater level impacts greatly. By stating the common hydrogeological problems about water delivery tunnel in water supply project, this paper described common problems existing in geological investigation for water diversion tunnel engineering, as rockburst, deformation of coffer rock, water gushing, putting forth the reasonable suggestion and protective measures.
