沙沱碾压混凝土坝施工期温度应力仿真分析OA北大核心CSCDCSTPCD
Simulation Study of Thermal Stress of Shatuo Roller Compacted Concrete Dam during Construction
结合沙沱碾压混凝土重力坝的工程实际情况,利用ANSYS软件及其二次开发技术,对该坝的典型坝段进行仿真分析研究.结合实测资料,对该坝段进行全过程温度应力仿真计算.分析了施工期温度及温度应力随时间变化情况以及某时刻在坝体的分布情况,总结了其变化规律.结合沙沱碾压混凝土重力坝埋设温度计的实测温度,将计算结果与实测温度进行了比较,表明有限元计算结果与实际情况相符,保证了仿真分析的准确性.计算表明,沙沱碾压混凝土重力坝施工期温度应力状况总体情况良好,但应特…查看全部>>
Using the ANSYS software and its secondary development technique, the simulation computation and feedback research of Shatuo roller compacted concrete (RCC) dam temperature field are realized, which is based on the practical situation of the construction of this RCC dam. The variation and the distribution of temperature and thermal stress in RCC dam in construction period are studied. The simulation results are consistent with the measured data of the thermo…查看全部>>
