严寒地区混凝土面板堆石坝施工技术的研究与应用

Study on Rock-Fill Dams with Concrete Face in Cold Conditions and Its Application

结合莲花水电站混凝土面板堆石坝的施工实践 ,重点研究严寒条件下面板堆石坝的施工技术 ,在冬季爆破参数、堆石料碾压参数、垫层料级配及碾压参数。

Based on practice in the construction of the rock fill dam with concrete face at the Lianhua hydropower station, studied are mainly the techniques used in the construction of rock fill dam under cold conditions, such as winter explosive parameters, roller compacting parameters of rock, cushion material gradation, coordinating ratio of roller compacting parameters and concrete face, anti crack measures, and so on. The result shows that the techniques are reasonable in the construction of rock fill dams with concrete face under cold conditions.
