气柜基础大体积混凝土施工质量监控与预测

Gas tank foundation of the mass concrete construction quality control and prediction

大体积混凝土的温度变化产生的温度应力导致混凝土产生温度裂缝,是大体积混凝土工程质量最重要的影响因素。结合工程实例,应用大型分析软件ANSYS进行仿真模拟,计算结果表明,温度场仿真计算值与实测值比较接近。为了控制大体积混凝土裂缝的产生,从原材料的选用、配合比的优化、双掺技术和设置循环冷却水管等方面采取了系列技术措施,确保了该大体积混凝土结构的施工质量。

Mass concrete thermal stress caused by temperature changes generate temperatures cause cracks in concrete, it is the mass concrete construction quality of the most important factor. With an example, application of large-scale simulation analysis software ANSYS simulation results show that the temperature field simulation and measured values are close. In order to control the production of mass concrete cracks ,from raw material selection, optimization of mixture ratio, admixture and set water cooling pipes, and has taken a series of technical measures to ensure the large volume construction quality of concrete structures.
