广昆铁路有砟轨道连续梁桥施工控制方法研究
|
摘要
桥梁工程的实际应用中,桥型的选择通常视跨径而定。在40-150m的跨径范围内,连续梁桥的应用居于主要地位,分析其原因在于连续梁桥具有变形小、结构刚度好、成本低、施工进度快、受力合理、行车舒适等优点,这使得其在我国的公路和铁路建设中均得到广泛应用。由于连续梁通常采用悬臂浇筑法施工,在施工的过程中,需要经历多次的结构体系转换,这导致桥梁线形控制的难度比较高,因此,有必要对悬臂浇筑施工的连续梁桥进行施工控制,并对施工控制方法进行研究。
本文以云南省广昆铁路工程禄丰双线特大桥(40+64+40)米连续梁桥为工程背景,针对该连续梁桥的特点,并结合现场的施工条件,提出了该连续梁的施工控制方案,详细的阐述了该连续梁的施工控制内容和方法,并对连续梁的线形、应力、温度进行了监控方法研究。
本文基于有限元分析方法,以“桥梁博士”软件系统作为计算工具,进行了连续梁桥悬臂施工过程的模拟和仿真计算,采用自适应控制系统、预测控制系统两种系统相辅助的方法来控制连续梁桥的施工过程。通过采集的现场实测数据和理论计算结果的对比、修正,以达到桥梁施工控制之目的。
在连续梁的整个施工过程中(从零号块的浇筑直至全桥成桥状态),通过施工控制的结果分析可知,桥梁结构的线形、应力均在设计允许的范围内,桥梁整体线形美观,施工控制效果较为理想。
In the practical application of the bridge engineering, the type of bridge is usually determined as the span. The span in the 40-150m scopes bridge, the application on the continuous beam bridge occupied the dominant position. The reason is that the continuous beam bridge has the advantages of small deformation, good stiffness, low cost, fast construction progress, reasonably stress, the driving comfortable and so on. So it is applied on highway and railway construction of our country. The structure of bridge complex, and need construct of repeated system transformation, and result of high difficulty in linear controlling, because the continuous beam cantilever construction. So it is necessary to construct control of cantilever construction of the continuous beam bridge, and research on the construct control method.
The engineering background of this article is the (40+64+40)meter continuous beam of Lufeng double big bridge in Guangtong-Kunming railway Engineering in Yun Nan. According to the features of continuous beam and construction conditions, draw up the program of construction control. And research on construction control method on the linear, stress, and temperature of continuous beam.
This article bases on the finite element method, and the "Doctor Bridge" software as a calculation tool, model simulation, and analysis, controlling the continuous beam construction, due to adaptive control system and predictive control system. By comparing the data of measured and theory, achieve the purpose of construction control.
In the whole process of construction control of the continuous beam, the result of construction control is that the structure of bridge's linear, stress close to the design. And the overall linear of the bridge is beautiful, and reached the more desired effect.
