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
