利用ANSYS软件及其二次开发技术,对普定碾压混凝土拱坝温度场进行了参数敏感性和仿真反馈分析研究.在此基础上,采用三维有限元法对该拱坝进行了全过程应力仿真计算.结合实测资料和计算结果,重点分析讨论了普定拱坝贯穿裂缝产生的可能原因,并针对碾压混凝土拱坝设计及施工提出了相关建议.以上研究提供了一种碾压混凝土拱坝温度场反馈分析及开裂仿真研究的初步思路,其分析结果对于类似工程具有一定的实际参考价值.

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 dams and the analytical results are also of practical value for the similar engineerings.
