张峰水库老马岭输水隧洞围岩工程地质评价

The Geological Evaluation on the Surrounding Rock Engineering of Laomaling Water Tunnel of Zhangfeng Reservoir

采用定性和定量的方法,根据《水利水电工程地质勘察规范》(GB50287—99)附录P,对张峰水库老马岭输水隧洞围岩进行了工程地质分类,对输水隧洞涌水、围岩稳定性进行了评价,并提出了相应的处理措施。

By using the qualitative and quantitative methods,and based on Appendix P of Code for Geological Investigation of Water Resources and Hydropower Engineering （GB 50287—99）,this paper classifies the surrounding rocks of Laomaling Water Tunnel of Zhangfeng Reservoir,evaluates the water flush of water tunnel and the stability of surrounding rocks,and puts forward some solutions.
