摘要
乌江构皮滩水电站地下厂房所处灰岩地区,地质条件复杂,存在岩溶、NW及NWW向断裂、层间错动、软弱夹层、软岩等主要地质问题。在经过前期近40余年的勘察研究所取得丰富勘察成果的基础上,就构皮滩水电站地下厂房存在的主要地质问题进行了系统分析,经过施工地质的验证,结论与前期的勘测成果基本一致。
The underground powerhouse of Goupitan Hydropower Station in Wu River is located in limestone rock area, where the geological condition is very complex, and many main geological problems such as karst, NW and NWW-trending rupture,intercalated sliding, weak interbed, weak rock are existed. The authors systematically analyzed these prob- lems on the basis of the abundant reconnaissance production which was acquired in the past 40 years, and educed important conclusion which was in consistence with the former reconnaissance results after the construction geology validation.
