三块田水库混凝土砌石重力坝设计计算

The Design calculation of concrete masonry gravity dam of San Kuaitian Reservoir

三块田水库是一座以灌溉为主兼人饮的C10细石混凝土砌毛石重力坝,最大坝高29.2m。由于原坝址上下游地质条件较复杂不适宜大坝建设,结合工程特性,对采用原坝址的坝型、枢纽布置和坝体结构进行了深入设计研究。推荐浆砌石重力坝,坝身溢洪道泄洪设计方案。经多次优化调整后,坝址及坝型选择、枢纽建筑物布置、坝体结构、坝基处理等均满足设计规范要求,为工程投资决策提供了重要依据。

The SanKuaitian reservoir dam is a C10 fine aggregate concrete rubble masonry gravity dam which the maximum height of 29.2m with functions of irrigation and drinking water supply.Since the geologic condi-tion of the original dam upstream and downstream area is complicated ,not suitable for dam construction ,com-bining the project characters,the deep design research for dam type,dam hydro building layout and dam structure based on the original dam site has been done.The masonry gravity dam ,and spillway release flood on dam design scheme has been recommended.After doing some optimization and adjustment of the design scheme,the dam site and dam type,the dam building layout,the dam structure and the foundation treatment can meet the design standard requirements ,it provides an important reference for project investment decision.
