Abstract: In the design of Hasang Hexi settling pond dam, four kinds of dam type were analysed, namely homogeneous earth dam, clay core wall dam, clay inclined wall dam and sand-gravel dam. On this basis, analytic hierarchy process was adopted in analysis on evaluation indexes, such as construction condition, engineering cost, construction period and management. As a result, homogeneous earth dam was selected as the Hasang Hexi settling pond dam type.

摘要： 哈桑河西沉沙调节池在工程设计中，对均质土石坝、粘土心墙坝、粘土斜墙坝以及砂砾石土石坝四种坝型进行了定性分析。在此基础上，运用层次分析法以施工条件、工程造价、施工工期以及施工工期运行管理等为评价指标进行定量分析，并选定了哈桑河西沉沙调节池工程坝型优选方案——均质土石坝方案。
