寒区抽水蓄能电站工程沥青混凝土心墙施工技术

Asphalt concrete core wall construction technology of pumped storage power station project in cold region

敦化抽水蓄能电站工程上、下水库防渗结构均为沥青混凝土心墙,由于地处高寒地区且水位往复变化,对其施工质量要求较高,通过一系列的室内及现场试验对施工技术进行优化改进,提出一套适宜的施工方案,并取得良好效果。

Asphalt concrete core wall is used as impervious structure in the upstream and downstream of Dunhua pumped storage power station.Because it is located in the high and cold region and the water level is reciprocating,its construction quality is higher.In this paper,through a series of indoor and field tests,the construction technology is optimized and improved.Based on the above,a set of suitable construction schemes have been proposed,and it achieves good results.
