| Abstract: | By using ANSYS software and its secondary development technique,the parameter sensitivity analysis,simulation computation and feedback research of Puding Roller-Compacted Concrete(RCC) Arch Dam temperature field are realized.Based on those researches,the behavior of the dam in the whole process is simulated by 3-D FEM.According to the numerical results and monitoring data,the possible causes of some cracks in the dam are further discussed;and advices on the design and construction of RCC arch dam are given.The research provides a basic idea of temperature field feedback analysis and cracking simulation of RCC arch dam;and the analytical results are also of practical value for the similar engineerings. |
