| Abstract: | In this paper,the conventional concrete bedding cushion of one gravity dam in alpine region in northern China is taken as the study object.With help of 3D FEM simulation calculation method and measured data,both temperature field and temperature stress field of the bedding-cushion concrete are inversed and analyzed.Causes for cracks in the bedding cushion concrete are demonstrated and necessity of provision of construction joint is studied.These demonstration and study can provide other projects with reference to prevent similar issues from occurring. |
