摘要
利用ANSYS软件及其二次开发技术,基本实现了碾压混凝土拱坝温度场全过程的仿真计算. 根据数值仿真计算并结合理论分析及我国首座碾压混凝土拱坝某些温度监测数据,得出了影响坝体温度场变化及其仿真计算可靠性的主要因素. 为检验普定拱坝温度场仿真分析结果的合理性,将仿真结果与实测值进行了比较分析,计算分析结果可为深入研究普定碾压混凝土拱坝真实工作性态提供参考依据,具有一定的工程应用价值.
By the use of ANSYS software and its secondary development technique, the simulation computation of temperature field for RCC arch dam can be realized rapidly. After the theoretical analysis and the comparison between the results of calculation and monitoring data of the first RCC arch dam in China,some main factors affecting temperature field and the reliability of its numerical simulation are presented.The numerical result of the temperature field, which can be helpful to find the cause of the crack in the Puding arch dam, is also given.
