新疆库巴格水库坝型比选分析

Analysis of dam type selection of a certain reservoir in Xinjiang

通过对地形地质、工程布置、防渗体耐久性、适应性及可靠性、工程施工及工程投资等方面进行综合比较,沥青混凝土心墙坝、混凝土面板坝均有筑坝条件,但沥青混凝土坝具有防渗性能好、施工工艺简单、投资相对较少等优点。综上所述,沥青混凝土心墙坝方案优于混凝土面板坝方案。因此选定沥青混凝土心墙坝为设计坝型。

Through the comprehensive comparison of geology,e ngineering layout,durability,adaptability and reliability of impermeable body,engineering construction and engineering investment,asphalt concrete core wall dam and concrete panel dam have damming conditions. But asphalt concrete dam has the advantages of good impermeability,simple construction technology and relatively little investment. In summary,the asphalt concrete core dam scheme is superior to the concrete panel dam scheme. Therefore,the asphalt concrete core wall dam is selected as the design dam type.
