摘要
红山水库放水隧洞全长1 156 m,其中压力洞200 m,无压洞956 m,隧洞的工程地质条件复杂。文中介绍了工程地质概况、存在问题。讨论了隧洞进出口位置的选择及设计,对隧洞围岩渗水中具有腐蚀性硫酸根离子的处理方案、隧洞初期支护方案和断层的处理措施。
The total length of Hongshan Reservoir＇s diversion tunnel is 1156 m,in it the length of pressure tunnel is 200 m,the length of free-flow tunnel 956 m.The tunnel＇s engineering geologic conditions are complex.The paper introduces its geologic situation and existing problems,discusses the selection of places of tunnel＇s inlet and outlet,states the treatment plan for the water which seeps from tunnel＇s surrounding rock,and in which the corrosive ion of sulphuric acid radical occurs,in addition,puts forward the support plan in earlier construction stage and fault-treating measure.
