Abstract: There are a large number of masonry dams in China, most of which use concrete face slab as upstream seepage prevention. Because of dam deformation and disrepair, many face slabs of masonry dam gradually fail and leak. It is necessary to build a new concrete face slab on the upper side of the old. The reliable combination of the new and old concrete face slab is the key to anti-seepage reinforcement, but the existing codes have not yet provided a mature technical scheme. In this paper, a technique scheme of combining anchorage and bond is proposed. Based on the monitoring result analysis of the project that has adopted the technology, it is indicated that the new technology can make reliable combination of the new and old concrete face slab.

Key words: masonry dam, anti-seepage face slab, combination, monitoring
