Masonry gravity dam type has been used widely in developing countries, in which China also has built many masonry gravity dams in the past. most of the masonry gravity dams have the structure of internal masonry and external reinforced concrete. Due to much internal masonry void, the dam upstream anti-seepage panel becomes the key part of its dam body anti-seepage system. After a long-time running, many masonry gravity dams’ upstream concrete panels have appeared many deficiencies such as aging, cracking, exposing steel bars and separating calcium, which have generated serious leakage problems, and then threatened the safety of the dams’ body and residents downstream, consequently the upstream anti-seepage panels should be restructured and reinforced with new techniques. This article summarizes technical difficulties and methods of masonry gravity dams’ upstream anti-seepage panels reconstruction and reinforcement, it also combined with an engineering project to introduce the new techniques and its effect of the upstream anti-seepage panel reconstruction and reinforcement.
