摘要
洗马河二级赛珠水电站碾压混凝土拱坝是高震区修建的首个采用2.5级配全断面碾压的混凝土双曲拱坝。大坝虽然高度不大,但地质条件复杂;大坝布置合理、技术先进。通过优化布置,既简化了施工条件、缩短了建设工期,又降低了工程投资,体现了显著的经济效益和良好的社会效益。电站于2004年8月开工,2008年下闸蓄水,同年8月工程完建。现大坝已经过2年的考验,整个坝体至今尚未发现裂缝,大坝运行安全正常。在同类工程中具有一定的代表性,可供借鉴。
Saizhu Hydropower Station,cascade Ⅱ on The Xima River,is the first concrete double-curved arch dam with 2.5 grading and full-section rolling built on high earthquake zones.The geological conditions are complex though the dam height is not high.The dam layouts are rational and advanced.The optimum of layouts simplified the construction conditions,shortened the time limit for the project,as well as reduced the investment.It has made marked economic benefits and good social benefits.The project has started at August in 2004,began store water in 2008,and completed at August in 2008.Now the two years past,there are not any cracks in the whole dam.The dam operation is safety and normal.It has a certain representative in similar projects,for reference.
