| 摘 要： | 结合百色碾压混凝土坝的工程实际情况，采用三维有限元浮动网格法对该坝施工期和运行期温度场、温度徐变应力进行了仿真计算。计算中考虑了混凝土热力学参数随龄期变化、坝体分层浇筑过程及自重、水压力对温度应力的影响。仿真结果给出了温度场、温度应力分布及其随时间变化规律，为碾压混凝土重力坝的设计和施工中的温控提供了参考依据。

| Abstract: | In this paper,three-dimensional finite element relocating mesh method is used to carry out the simulation calculation of the temperature field and thermal stress field of the Baise RCC dam during construction and operation period.The impacts on thermal stress of concrete calorific and mechanical parameters varying with time,the process of dambody pouring by layers,the gravity of the dam and water pressure are considered in calculation.The change laws of temperature field and thermal stress with time and their distributions are suggested;whereby providing the reliable basis for the dam design and for taking corresponding temperature control measures during the dam construction. |
