Application of splitting grouting on the dam reinforcement

Abstract

As one new type of the technology on the dam reinforcement, the splitting grouting has been established only in China since 70 and applied in a lot of dam reinforcement. The thickness of splitting grouting, deformation of the dam and the seepage field of grouting are important keys in dam reinforcement by splitting grouting. However, the theory of splitting grouting has not been known widely and lacked system generalizing. In the paper, the theory of splitting grouting is detailed statement and some actual projects are introduced to analyze the deformation of the dam before and after the splitting grouting. Moreover, the stability of the dam by using finite difference method are simulated and analyzed. The conclusion of analysis is consistent with the in-site observation. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
