我省南溪水库砌石拱坝,坝高67.3米,坝顶长226.0米,系我省目前规模最大的砌石拱坝。工程于1975年开始砌筑,1981年年底基本建成蓄水,1983年竣工。主要由于水泥供应紧张,以致经常停工待料,施工期较长。大坝采用细骨料砼砌条块石,砼一般占55％左右。原设计大坝由整体砌筑,不设横缝。设计荷载考虑了水压力、泥砂压力、自重和按经验公式 Nanxi Reservoir Masonry Arch Dam in our province, the dam height of 67.3 meters, 226.0 meters long top, the Department of the province’s largest stone masonry arch dam. Construction started in 1975 masonry, basically completed by the end of 1981, water storage, completed in 1983. Mainly due to tight supply of cement, resulting in frequent suspension of work to be expected, the construction period is longer. Dam using fine aggregate concrete block stone, concrete generally accounts for about 55%. The original design of the dam by the overall masonry, no transverse joints. Design loads take into account water pressure, sand pressure, weight and empirical formula
