Abstract

The asphalt concrete core wall has been widely used in various kinds of high dams because of its good performance of anti-seepage, deformation and rapid construction speed. In recent years, the leakage phenomena of some asphalt concrete core dams begin to occur, endangering dam safety. To determine the leakage status, location and access of the bituminous concrete core, drilling holes are arranged in the upper and lower reaches of the bituminous concrete core wall. With water as the medium, underwater sonar, color TV observation in hole, consecutive test of tracer, water level analysis in the dam body and physical detection and other methods were used for detection. Then the leakage state of asphalt concrete core wall of dam body is comprehensively analyzed and determined according to a variety of test results. At the same time, aiming at the problems existing in the direct repair of asphalt concrete core wall in the dam body, repairing project of concrete seepage cut-off wall, controlling grouting repair scheme, as well as its key control factors, construction process and technical parameter indexes were studied. Through the application of multiple engineering examples, the treatment effect was remarkable, which can provide a reference for the treatment of similar engineering problem.
