Analysis of Thermoelastic Characters and Leaking Repair for the Long Spruce Dam

摘要

This paper deals with the temperature and displacement fields of the top mid block of south transition at Long Spruce Generating Station, in the North of Manitoba, Canada. According to the experimental results of Manitoba Hydro in the past two years, the top mid block is assumed to be a rectangular one that has two supposed temperature distributions at its boundary sides. Then, the temperature fields for the top mid block are obtained from the analytical solutions by separation of variables. By using the analytical solution of temperature field, the displacement behavior of the top block in various temperature fields is discussed in details. The numerical results are given to show the causes of the leakage between the top mid block and the dam. Finally, the repair methods for leakage are discussed for practical leaking repair and its engineering applications.
