Temperature Field Simulation of Caohe Aqueduct during Construction Period
【摘要】 混凝土结构施工期温度场的分布是产生裂缝的主要因素之一。利用三维有限元软件对实际结构进行全过程仿真分析,通过确定混凝土浇筑温度、间歇期及养护温度,来控制混凝土在施工期温度场的分布。
【Abstract】 The temperature field distribution of concrete structure in the construction period is one of the main factors for cracks of concrete.3D finite element software is used to carry out entire process simulation analysis of the actual structure in this paper.The temperature field distribution of concrete structure in the construction period is controlled through controlling the temperature of pouring,diapause and maintenance.
