摘要
守口堡水库大坝采用的是胶凝砂砾石坝。这是我国首次将这种新坝型用于永久性水利工程中。结合工程当地材料情况,并同国内外工程进行类比,对坝体断面、坝体材料分区、建基面设置、泄洪建筑物布置等方面进行分析研究,得出了守口堡水库胶凝砂砾石坝的合理设计方案。守口堡水库胶凝砂砾石坝最大坝高为61.6 m。坝体断面型式为上下游坡比1:0.6的梯形断面。按照材料性能的不同,大坝断面划分成6个分区。大坝主体为胶凝砂砾石。坝体上下游分别设置防渗层和保护层、大坝建基面比混凝土重力坝放宽、泄洪建筑物布置于坝体。
The adopted dam type in the Shoukoubu Reservoir is a cemetend sand-gravel dam. It is the first time to use this new dam type in permanent hydraulic project in our country. In combination with the local material situation and by comparison with the similar project at home and abroad, the cross section of dam, material zoning of dam body,foundation surface setting and spillway structures layout are studies, and the reasonable design scheme is obtained. This reservoir＇s maximal dam height is 61.6 m. Its trapezoidal cross section has the same dam-slope ratio 1：0.6 for the upstream and downstream surface. The cross section is divided in 6 different regions according to the material characters.The main core material of dam is the cemented sand-gravel and the impermeable concrete layer and protective concrete layer are set on the dam upstream and downstream. The width of dam foundation is wider than a concrete gravity dam.The spillway structures are set on or in the dam body.
