葵型拱桥落架过程仿真分析

Simulation Analysis of Removing the Sunflower Tape Arched Bridge’s Scaffolds

本文以有限元法为理论基础,通过ANSYS软件建立子牙河桥的全桥结构仿真模型,结合子牙河桥的实际施工过程,采用桥梁施工控制方法中的正装迭代法对钢筋混凝土葵型拱桥满堂支架落架施工控制进行分析,按照桥梁落架的施工过程进行仿真分析计算,提出切实可行的落架方案,对施工过程进行理论指导,确保施工过程中桥梁的安全,降低施工难度,加快施工进度。

Based on the finite element method, the entire structure simulation model of the Ziya River Bridge was established by the software ANSYS. Combining the actual construction process of the Ziya River Bridge, the positive sequence repetitive process of the bridge construction control method was used to analyze the construction control of the scaffolds＇ removing, which are used for the full support of the reinforced concrete sunflower tape arched bridge. The simulation analysis and computation were made according to the construction process of the scaffolds＇ removing and the reasonable method was proposed tu instruct the construction process. The construction security was ensured and the difficulty of construction was reduced so to speeding up the construction progress.
