| 摘 要： | 温度的变化及其产生的影响在碾压混凝土拱坝中是不容忽视的,本文利用三维有限元法,对某碾压混凝土拱坝进行了全过程仿真分析。在分析中考虑了混凝土绝热温升随龄期的变化、通水冷却、分层浇筑和夏季停工渡汛等因素,得出了温度场分布及其随时间变化规律,为该坝的设计与施工中的温控防裂提供参考。

| Abstract: | It is not neglected that temperature change and the effect of temperature field on RCC arch dam.The whole process simulation analysis of a RCC arch dam is done with 3D FEM.The factors,such as: the change of adiabatic temperature along with age of concrete,pipe cooling,concrete placing by layer,work suspension in summer,are considered in the analysis.The change laws of temperature field along with time and its distributions are provided in the calculation results,which could be used as one of the references for temperature control and crack prevention in the design and construction of the RCC arch dam. |
