摘要
落脚河水电站拦河大坝是一座外掺MgO不分横缝的拱坝,在施工图阶段通过对坝址地质条件深入细致的研究,将初步设计阶段的等厚水平拱圈优化为变厚的椭圆线形拱圈的双曲拱坝,在使坝体应力水平满足要求的前提下,节省了坝基开挖及坝体混凝土工程量。
The dam of Luojiaohe Hydropower Station is one without horizontal joint made of concrete with MgO. On the period of designing construction drawings constant-thickness horizontal arch in primarily design period was modified to different-thickness elliptic one after research on geologic conditions of dam site in details and optimum. The result not only met the requirement of stress, but also cut down the volume of the dam and excavating work.
