Design of Mixed Concrete Core Wall with Asphalt in Guanmaozhou Power Station

官帽舟水电站挡水坝设计采用碾压式沥青混凝土心墙混合坝,坝体填筑料充分利用泄洪建筑物的软岩开挖料。通过沥青混凝土防渗材料试验结果和防渗体应力应变分析,选择沥青混凝土混合坝坝型是经济可行的。

The rolled concrete core wall mixed with the asphalt was constructed in the retaining dam in Guanmaozhou Power Station and the soft rock excavated material from the excavation of the flood-releasing works can be fully used as the filling in the mass of the dam. The analysis of both the impermeable bituminous concrete material test result and the core wall stress strain has proved that the type of the composite dam with the bituminous concrete be economically feasible.
