本文针对云南大型水电站建设中鲁布革工程的坝型选用、毛家村工程的坝基处理及漫湾水电站的施工导流等重大技术问题,作了反思,从中认识到:坝型选择必需坚持最大的综合经济效益;对坝基处理必需充分论证技术方案,避免施工中方案更易;导流方式要在依据地形地质、水文特性的同时,更充分发挥枢纽布置和坝型特征优势以及泄水建筑物的综合利用。
In this paper, in light of the major technical problems such as dam type selection of Lubuge project, dam foundation treatment of Maojiacun project and construction diversion of Manwan hydropower station during the construction of large-scale hydropower stations in Yunnan Province, the author realized that dam type selection must adhere to the largest Comprehensive economic benefits; the treatment of the dam foundation must fully demonstrate the technical solutions to avoid the construction of the program easier; diversion approach should be based on the topography and geology, hydrological characteristics at the same time, give full play to the hub layout and dam-shaped features and advantages of integrated drainage building use.
