摘要:
不同厚度大体积混凝土板施工过程中温度场不同,其相邻温度场在施工过程中会相互影响,对其影响规律进行研究,可为解决大体积混凝土施工过程中的技术难题提供参考依据。文章利用ANSYS软件设计了4种不同厚度的混凝土基础底板组合形式,通过模拟温度场变化情况研究了不同厚度大体积混凝土基础底板温度场的相互影响,并对实际工程中的大体积混凝土基础底板进行了温度监控,结合实测数据与数值模拟进行了对比分析。结果表明:相邻不同厚度大体积混凝土板交界处,温度场的相互影响较大;水平方向距离交界位置越远,相互影响越小;相邻板越厚,相互影响越大;交界处混凝土最高温度没有出现在板厚的中间位置,而出现在交界深度中间偏下的位置。
Abstract:
The temperature fields of mass concrete with different thickness are different during construction. The adjacent temperature fields will affect each other during the construction process, study the mutual influence laws, and provide reference for solving the technical problems in the construction process of mass concrete. This paper uses ANSYS software to design four different thickness concrete base plate combinations. The interaction between the temperature fields of mass concrete base plates with different thickness was studied by simulating the temperature field changes. The temperature of the mass concrete base plates in the actual project was automatically monitored, and the measured data was compared with the numerical simulation. The results show that the temperature field interaction of mass concrete slabs with different thicknesses is larger at the junction.The farther away from the boundary, the smaller the mutual influence; The thicker the adjacent plates, the greater the mutual influence; the highest temperature of the concrete at the junction does not appear in the middle of the plate thickness, and appears at a position below the middle of the boundary depth.
