摘要：

Through application of a series of techniques consisting of small caliber drilling, grouting procedure from top to bottom, the orifice of grouting holes blocked out and recycling grouting in the holes, a kind of high pressure has been used to dam foundation grouting for China Three Gorges Project. During the course of grouting, milled grout is perfused in remoteness cracking rock, epoxy resin is done to enhance bedrock strength in faultage rock stratum, and at orifice section acrylate materials are used to enhance impermeability, in the place of profound permeable zone in riverbed many construction methods such as grouting, consolidation and regrouting. Many on spot measurement and survey data indicate that construction methods are reasonable and effective.
