摘要
介绍益阳茅草街大桥(钢管混凝土中承式系杆拱桥)1∶20模型试验主拱合龙后的施工模拟过程,探讨了仿真分析计算模型的建立,将仿真计算与实测结果进行对比,从而验证了仿真计算的准确性以及施工工艺的可行性和安全性。
This paper introduces the 1 ： 20 model test and simulation of construction process after closure of the main arch of the Maocaojie Bridge （a half-through concrete-filled steel tube tied arch bridge） in Yiyang, discusses the establishment of the model for the simulation analysis and calculation, compares the results of the calculation with those of the field measurements and consequently verifies the correctness of the calculation, and feasibility and safety of the construction technology.
