Simulation and inversion analysis on working behavior of super-high arch dam of Jinping Ⅰ Hydropower Station
摘要
Abstract
The arch dam of Jinping I Hydropower Station is 305 m high.The full construction process of the dam from the beginning of the concrete placement to the impounding and operation is simulated with the method of the finite element simulation analysis,and then the inversion analyses on the main thermodynamics parameters,such as the late heat-generation and temperature rise,dam body and its foundation elastic modules,etc.,are made,while the working behavior of the next impounding stage is predicted as well.The calculation result shows that the late heat-generation and temperature rise of the dam is about 5 ～ 6 ℃ and the elastic modules of concrete and foundation are about 1.65 times of the initial design values.When the water level reaches up to El.1 880 m,the radial deformation occurs at the location of El.1 730.0 m of PL13-4 monitoring point.Basically,the predicted values better coincide with the monitored ones,thus it is demonstrated that the actual working behavior can be generally reflected by the results from the simulation analysis,moreover,the analysis results can provide references for the design of the other super-high arch dam concerned as well.关键词
