摘　　要：其宗水电站坝址河床及阶地分布的覆盖层，不仅厚度大，且成因复杂。覆盖层的工程地质特性及建坝适宜性是本工程的重大工程地质问题之一。通过合理有效的勘探手段和多种室内、外测试和试验方法，对覆盖层的分布特征、成因类型、工程地质特性及建坝适宜性进行了深入研究，提出了科学、合理的覆盖层分层及有关地质参数建议值，为工程的方案选择、坝基处理设计等提供了可靠的地质依据。The covering layers distributed at the dam bed and terrace of Qizong Hydropower station not only has large thickness, but also has complex cause of formation. The engineering geological characteristics of the covering layer and the suitability for dam construction are one of the major engineering geological issues of this project. Through reasonable and effective means of exploration and various indoor and outdoor testing methods, an in-depth study on the distribution characteristics of covering layer, causes of formation, engineering geological characteristics and suitability for dam construction has been made and the scientific and reasonable lamination of covering layer and the relevant suggested values for geologic parameter are put forward, so as to provide a reliable geological basis for the solution selection of this project and the treatment design of dam foundation.
