| 摘 要： | 设想南水北调延伸工程西线剪刀峡方案由大昌取水口、四个槽经椿树坪至剪刀峡隧洞、剪刀峡水库、檀木取水口、檀木至茅草坡隧洞及堵河下游梯级水库串联而成.概括介绍了取水口和相关隧洞及区域工程地质条件,分析评价其工程地质适宜性和相关环境工程地质问题.研究认为,西线剪刀峡(檀木-茅草坡)方案一级泵站大昌八角丘场址工程地质条件优越,剪刀峡水库库尾二级取水泵站檀木场址工程地质条件适宜;春树坪至剪刀峡隧址区地表岩溶发育,岩溶涌水、涌泥是该隧洞段关键性工程地质问题;檀木至茅草坡深埋长隧洞存在局部岩溶涌水尤其是近河断裂接触性岩溶涌水等工程地质问题.

| Abstract: | The Jiandaoxia line consists of two-stage pumping station,two long tunnels and related reservoirs,which is the west route scheme of diverting Da'ning River to Han in the South-North Water Transfer Project. The paper introduces the regional geoengineering condition of the pumping station and related tunnel,and analyzes its property and related environmental and engineering problems. |
