摘要
以大跨度连续梁主墩大体积承台基础为研究对象,通过有限元分析软件midas civil模拟温度场分布,用来设计和优化施工中的保温降热措施,减小混凝土内外温差,有效避免了裂缝的产生,本工程的经验,对类似施工中的优化温控和防裂措施,有一定的借鉴作用。
The large-scale continuous-girder pier main bulk foundation platform was used as the research object.The finite element analysis software midas civil was used to simulate the temperature field distribution.It was used to design and optimize the heat-preservation and heat-reduction measures during construction,and reduce the temperature difference between the inside and outside of the concrete,thus avoiding the occurrence of cracks.The experience of this project can be used as a reference for optimization of temperature control and crack prevention measures in similar constructions.
