用三维有限元浮动网格法进行了水电站表孔闸墩施工期的温度场和温度应力仿真分析 ,分析中考虑了混凝土的弹模、徐变度及自生体积变形等物理力学参数随龄期变化和分层浇筑对墩体温度应力的影响 ,提出了防止在施工过程中由于外界温度变化及混凝土水化热等因素引起表面裂缝的措施
The three-dimensional finite element method of floating grid method was used to simulate and analyze the temperature field and temperature stress during the construction of the pier for pier of a hydropower station. The physical and mechanical parameters such as the elastic modulus, creep degree and autogenous volume deformation of the concrete changed with the age And layered pouring on the pier temperature stress, put forward to prevent the construction process due to external temperature changes and concrete hydration heat and other factors caused the surface cracks in the measures
