高面板坝SR塑性止水材料周边缝模拟试验

Simulation test on peripheral joint of SR plastic sealing materials for high concerete face dams

ＳＲ塑性止水材料是专为混凝土面板堆石坝周边缝和伸缩缝止水而研制的，具有塑性大、耐高低温、延伸性大、耐老化、与基面粘接性强、水中有自愈性和冷操作施工等特性。周边缝模拟试验表明，为高面板坝研制的ＳＲ－３塑性止水材料具有更大的延伸性和缝变形适应能力，可作为高面板坝接缝可靠的防渗材料。

SR plastic sealing materials are developed for sealing peripheral joints and expanded joints of concrete face rock-fill dams. The materials are characterized by high plasticity, large elongation, resistance to high and low temperatures, ageing-resistance, high stickiness to host surfaces, self-repairing in water, and cold construction. Simulation test of peripheral joints showed that SR-3 plastic sealing material has larger elongation and higher adaptability to the deformation of joints. It can be used as a reliable joint sealing material.
