摘要
根据地形、地质条件及当地筑坝材料分析,以纪柯坝址为典型代表的西线一期工程中其河谷形状较好、坝基覆盖层较薄的高坝坝址,具备修建混凝土重力坝和混凝土面板堆石坝及沥青混凝土心墙坝的条件。进一步的研究和论证结果表明,修建混凝土重力坝和混凝土面板坝及沥青混凝土心墙坝在技术上均可行,混凝土面板堆石坝及沥青混凝土心墙坝方案在投资、工期及施工方面,优势明显。
According to the topographical,geological conditions and analysis of local materials,Jike site,which is one of the typical high-dam sites in first stage of the Western Route water-transfer project,has an appropriate valley shape and a thin alluvium deposit.Three dam types（concrete gravity dam,concrete faced rock-filled dam and embankment dam with an asphaltic concrete core） are convenient for construction in this site.Further studies and comparisons indicated that these three dam types are technically feasible,concrete faced rock-filled dam and embankment dam with an asphaltic concrete core had distinct advantage in cost,project period and construction.
