通过进行心墙垫板裂缝渗流及充填保护试验,分析了在裂缝上游侧设粘土保护层的作用效果,比较了不同裂缝开度和围压对坝体抗渗性的影响。结果表明这种新型保护措施可以较好地保护心墙粘土不被坝基裂缝中的水流冲刷,并能对裂缝进行部分充填,使遭到破坏的防渗体性能逐渐恢复。试验的各项结果符合工程实际。
The effect of clay protective layer on the upstream side of the fracture is analyzed through the crack seepage and filling protection test of the core wall plate. The influence of different crack opening and confining pressure on the impermeability of the dam is compared. The results show that this new type of protective measures can better protect the core wall from water erosion in the dam foundation cracks and partially fill the cracks so as to gradually restore the damaged barrier fluid. The test results in line with the actual project.
