RESEARCH ON STRUCTURAL MODEL TEST OF BOTTOM JOINT OF ASPHALT CONCRETE CORE WALL IN EARTH-ROCK DAM

摘要

Bottom joint between the asphalt concrete core wall and the concrete waterproof wall is the key structural part of the whole core wall seepage-proof system. whether it is good or poor will have a direct impact upon the safety operation of core walls as well as upon the seepage proof effects. This paper suggests a method for conducting structural model test study of bottom joint of asphalt concrete core wall. The corresponding test device is developed and used to carry out the test study of the structural types of plane connection with core wall bottom joint. The test results prove that the utilization of plane connection type for the core wall bottom joint is rational and reliable.
