阿勒泰市乌拉斯特水库沥青混凝土心墙堆石坝

阿勒泰市处于高寒地区,冬季漫长,施工工期比较短,新建一座水库一般需要3年时间完工;而沥青混凝土心墙坝可在较低温度下施工,施工期较长,对坝基坝体变形适应性强,心墙自愈能力好。本文以乌拉斯特水库为例,介绍了其混凝土心墙堆石坝的坝体分区、防渗体结构设计、沥青混凝土与基础和岸坡的连接、沥青混凝土心墙配合比设计和坝肩及坝肩防渗处理,供同类工程参考。

Asphalt Concrete Core Wall Rock-fill Dam of Altay Urasty Reservoir

Altay is located in alpine region, which is characterized by long winter and relatively short construction period, therefore constructing a new reservoir generally takes three years. Asphalt Concrete Core Wall Dam can be constructed under lower temperature with longer construction period, strong adaptability to deformation on dam foundation and dam body, and strong self-healing ability on core wall. In the paper, Urasty Reservoir is adopted as an example for introducing dam division of concrete core wall rock-fill dam, impermeable material structure design, connection among asphalt concrete, foundation and bank slope, asphalt concrete core wall mix proportion design, and anti-seepage treatment between dam abutments, which is provided as reference for similar projects.
