混凝土面板坝止水带设计与柔性填料

Design principles of watertight strip for high reinforced concrete face dam and the control indexes of flexible filling material performances

1998年以前完工的 30座 10 0m以上的面板坝中 ,有约 1 6的坝蓄水后漏水量大而采取了减少漏水的工程措施。为提高 10 0m以上高面板坝止水的安全可靠性与耐久性 ,对其止水带结构型式及柔性填料的性能等进行了研究 ,提出了高钢筋混凝土面板坝止水带的设计原则 ,阐述了柔性填料的工作原理并确定了性能控制指标。

Among thirty concrete face dams each with the height of over 100 m that had completed before 1998, about 1/6 of these dams have adopted engineering measures to reduce leakage volume because of big leakage after impoundment. In order to enhance the safety, reliability and durability of watertight for high concrete face dam, the structural type of watertight strip and pre placed filling material performances have been studied and the design principles of watertight strip for high reinforced concrete face dam have been put forward. Meanwhile this paper also describes the working principle of flexible filling material and determines the control indexes of its performances.
