| 摘 要： | 经过初步计算、反分析计算和反馈计算对二河新泄洪闸施工期混凝土的温度和应力变化进行了数值仿真分析，并应用于指导施工，最终在水闸施工过程中没有出现肉眼可见裂缝。实践证明只要施工方法合理，事先进行充分研究工作，完全可以实现不出现肉眼可见裂缝的防裂目标。

| Abstract: | Numerical simulation and analysis are conducted through preliminary estimate, reverse calculation, and feedback calculation of the concrete temperature and stress during the construction period of the new Erhe Sluice. The results are used to guide the construction, and no crack visible by naked eyes occurs in the construction process. It is proved by the application that as long as the method is rational and the work is studied fully, the goal of prevention of crack visible by naked eyes can be reached. |
