| Abstract: | In order to analyze the different causes of various cracks in Xiajiang Hydro-junction,the sluice bottom is simulated with the nonlinear finite element method(FEM),combining the stress and temperature experimental data obtained from the dam safety monitoring process.Through the comparison and analysis of actual conditions and the results with the actual distribution of cracks,it is concluded that the primary factors causing different kinds of cracks are infrastructure constraints and temperature stress.The paper proposed some specific measures of prevention and treatment of cracks. |
