地震裂缝处理方法与实践

Disposal method of earthquake fissure and practice

经过东洱河水库和大河边水库工程在地震后产生的裂缝,采用充填灌浆方法进行处理,地震裂缝内形成了坚实的连续有效的水泥黏土混合浆体,提高了坝体的密实度,增强了坝体抗变形的能力,从而达到了地震产生裂缝处理的预期目的。

Through adopting the method of filling grouting to dispose the earth quake fissure at the engineering of Dongerhe Reservoir and Dahebian Reservoir,a solid consecutive valid slurry of compounded cement-clay in the fissure is formed;and then the compactness of dam body and the ability of resisting deformation of dam dody are improved,thus achieving desired filling results for coming into being the fissure subsequent in time to earthquake.
