在金沙江溪洛渡电站正式开工前, 本刊记者采访了三峡工程质检专家组副组长、中国工程院院士谭靖夷。谭靖夷就金沙江溪洛渡工程的设计优化、施工质量谈了自己的看法。溪洛渡工程跟二滩、小湾,拉西瓦不一样。它的规模大、工程量大、装机容量大,特别是地下洞挖工程量大。溪洛渡水电站装机1260万千瓦,左、右岸两个地下主厂房对称,混凝土浇筑量很大,除去优化的150万方,混凝土有1500 万方。另外,溪洛渡工程的泄洪流量也比小湾大。从泄洪规模上看,无论国内还是国外的水电站,目前溪洛渡电站都是第一。溪洛渡水电站地形地质条件很好。地形对称。地质主要是玄武岩,偶尔夹有灰岩,但总的来说很好。坝型设计究竟采用哪种曲线,这要看当地的地形, 以可利用基岩面为基准来决定。辟如, 是采用对数螺旋线还是抛物线。不是某
Before the official start of the Xiluodu hydropower station on the Jinsha River, our reporter interviewed Tan Jingyi, the deputy leader of the Three Gorges Project Quality Control Expert Team and the academician of the Chinese Academy of Engineering. Tan Jingyi on the Jinsha River Xiluodu project design optimization, construction quality talked about their own views. Xiluodu project with Ertan, Cove, Lasiwa is not the same. Its large scale, large quantities, large installed capacity, especially in large underground tunneling projects. Xiluodu Hydropower Station installed 12.6 million kilowatts, left and right bank of two underground plant symmetry, a large amount of concrete pouring, remove the optimized 1.5 million square, 15 million square concrete. In addition, Xiluodu flood discharge project than the small Bay. From the perspective of flood discharge, both domestic and foreign hydropower stations, the current Xiluodu Power Station are the first. Xiluodu Hydropower Station topography and geological conditions are good. Symmetrical topography. Geology is mainly basalt, occasionally sandstone, but in general good. What type of curve should be used for dam design depends on the local topography and can be determined on the basis of available bedrock surface. For example, is the use of logarithmic spiral or parabola. Not a
