| Abstract: | By using three dimension linear elastic finite element(FEM)and the software ANSYS, a FEM model is established for reflecting the interaction between the concrete of dam body an rock mass of dam foundation . Through simulating different thermal-structure interaction loadcases, the dam body's stresses and strains under the effect of multi-loads during operation period were analized with order coupled analysis method. The calculation results indicate that the stress and deformation of the arc dam accord with t... |
