摘要
为了提高寒潮作用下大体积混凝土闸墩温控防裂仿真计算的精度，应用ANSYS软件，在运用APDL语言编制仿真程序的过程中将子母模型联合反馈修正算法应用于闸墩混凝土随时间变化的温度和应力计算中。以双台子河闸工程为例，采用该算法得到的温度场及应力场与实际情况相符，计算精度较高。
In order to improve the calculation accuracy on temperature control and anti-cracking of mass concrete sluice pier under cold wave, the sub-master model correction algorithm is applied in simulation program development based on APDL language of ANSYS to calculate the temperature and stress of concrete with time change. The application of this algorithm in Shuangtaizi River Sluice Project shows that the calculation results of temperature and stress fields are consistent with actual situation and has higher calculation accuracy.
