浅析荔波县拉寨水库枢纽坝型比选

Comparison and Selection of Dam Types of Lazai Rervoir in Libo County

结合荔波县拉寨水库枢纽概况,根据选定的下坝址水文、地形及地质条件,坝型选择了重力坝和钢筋混凝土面板堆石坝坝型进行比选,从工程地质条件的适宜性、建筑物布置、施工条件等技术经济方面进行比选,最终选择重力坝方案,施工技术简便,布设紧凑,经济性较高。

Based on the general situation of Lazai Reservoir in Libo County,the scheme of gravity dam is compared with the scheme of reinforced concrete face rockfill dam according to the hydrology,togopraghy and geological conditions of the dam site. Finally,the scheme of gravity dam is selected considering the suitability of engineering geological conditions,the layout of hydraulic structure,construction conditions,etc. The construction technology of the selected scheme is simple,the layout is compact and the economy of the scheme is high.
