摘要
对三门核电站1号核岛底板混凝土浇注实测温度结果进行了分析,并运用Matlab编程,采用一维及二维差分法对混凝土浇注及养护过程温度场进行模拟。通过结果的对比表明,差分法在预测混凝土温升方面具有较好的准确性和良好的工程实用性,二维差分法计算结果与实测结果较为一致且具有更高的精度,可以用于模拟混凝土温度场及应力场。
Based on the one and two dimensional difference method,use Matlab to simulate the Concrete Hydration Heat of Sanmen Unit 1 NI Basemat.The comparison between the simulated results and the actual measurement shows that the difference method has good accuracy and good practicability to evaluate the maximum temperature of the newly poured concrete.The results of two dimensional difference method are more consistent with the measured results and it also has high accuracy.It could be used to simulate the temperature field and stress field.
