摘要
为了掌握三里坪大坝施工期及蓄水过程中坝体温度场和应力场分布情况,判断大坝安全性状,并为制定大坝温控措施及分缝方案提供依据,运用有限元方法进行仿真计算;结合大坝混凝土分区及分缝与浇筑方案以及温控标准,介绍了应力仿真计算成果,分析了可能出现的工程问题及相应的防范措施。其分析计算成果验证了所采取温控措施及分缝方案的合理性。
In order to obtain temperature field and stress field of Sanliping RCC dam during the construction and impoundment period so as to determine the safety status of the dam and provide a basis for the scheme of temperature control and jointing,FEM was adopted to conduct a simulation.Combing with the condition of concrete zoning and jointing and temperature control standard,the simulated results are presented and the potential problems and relative measures are analyzed.The rationality of temperature control and jointing scheme is verified by simulated results.
