Thermal Regime of the Downstream Shoulder of Rockfill Dams (Termicheskii Regim Nizovoy Prizm Kamennona'Rosnoy Plotin),
Abstract
A system of equations describing the thermal regime of rockfill dams, one taking natural air convection into account, is presented in the paper. A numerical solution of the equations is given for the profile of the downstream shoulder of the rockfill dam of the Vilyuy Hydroelectric Power Plant, the solution being obtained with the aid of a computer. The results of calculation and of field observations are found to be in close agreement. This paper is devoted to study of the thermal regime of the downstream shoulder of rockfill dams. Calculation of the thermal regime of the downstream shoulder is necessary in order to establish the thermal state of the apron (core), the base of the dam, and the location of drainage installations. The thermal regime of the downstream shoulder of a rockfill dam is formed as a result of conductive heat transfer and convective heat transfer by the air moving in the pores. (Author)
