文章结合混凝土连续刚构桥自身及施工方式的特点,以龙溪河大桥为工程实例,比较了几种模拟算法运用于混凝土连续刚构桥施工控制中的优缺点,认为在混凝土连续刚构桥施工控制中,正装计算法要明显优于其他方法,并对正装计算法缺陷进行了改进,提出了相应的改进方法。结论表明,改进前后结果差别不大,可见现有正装计算法即能满足要求。
Combining with the characteristics of concrete continuous rigid frame bridge and its construction method, taking Longxi River Bridge as an example, the advantages and disadvantages of several simulation algorithms used in the construction control of concrete continuous rigid frame bridge are compared. It is considered that in concrete continuous rigid frame bridge In construction control, the formal calculation method is obviously better than other methods, and the defects of formal calculation method are improved, and the corresponding improvement methods are put forward. The conclusion shows that there is not much difference between the results before and after the improvement, indicating that the existing formal calculation method can meet the requirements.
