摘　　要：糯扎渡工程在可行性研究阶段,比较了直心墙堆石坝和斜心墙堆石坝两种方案,分析表明,直心墙堆石坝在坝坡稳定性、坝体应力及抗震性方面均满足设计要求,且在地形地质条件、基础处理、抗震性能、施工方便性、工程造价等方面不同程度地优于斜心墙堆石坝,因此,设计最终选择直心墙堆石坝方案。The comparison of two alternatives, that is, the rockfill dams with vertical core and inclined core, is carried out. The analysis showed that the rockfill dam with vertical core can meet the requirements of design in following aspects, stability of dam slope, the stresses of dam body and earthquake resistance. And it has more advantage than that of another alternative in following aspects: topographic and geologic conditions, foundation treatment, ability of anti-earthquake, construction condition, and project cost.
