Water pipe cooling is mainly used to control temperature during the construction of mass concrete structures. How to accurately simulate the temperature field of mass concrete under the action of water pipe cooling is very important. This paper presents a new method for simulating the temperature field of a mass concrete with the water pipe cooling. In this method, the contact surface of the water pipe and the concrete is used as the heat dissipation surface into the control equation, and the composite Multiquadrics radial basis function (MQ-RBF) and low-order linear polynomial combination are used to discrete the spatial domain. Because the heat dissipation surface of the water pipe is included in the boundary conditions, there is no need to build the refined water pipe modelling. This new method not only reduces the calculation cost, but also ensures the calculation accuracy. Through four calculation examples, they show that the algorithm has advantages in the numerical simulation of the concrete temperature field with water pipe cooling.

管水冷大体积混凝土热场数值模拟

水管冷却主要用于大体积混凝土结构施工过程中的温度控制。如何准确模拟大体积混凝土在水管冷却作用下的温度场非常重要。本文提出了一种模拟大体积混凝土水管冷却温度场的新方法。该方法以水管与混凝土的接触面作为散热面进入控制方程，采用复合Multiquadrics径向基函数(MQ-RBF)和低阶线性多项式组合离散空间域。由于水管的散热面已包含在边界条件中，因此无需构建精细的水管建模。这种新方法不仅降低了计算成本，同时也保证了计算的准确性。通过四个算例，表明该算法在水管冷却混凝土温度场数值模拟中具有优势。
