基于ANSYS平台斜连续箱梁桥顶推仿真分析程序二次开发

摘要
我国是一个多山的国家,特别是在西部,山谷沟壑众多,因此在西部山区修建高等级公路受地形、地貌和地质条件的限制以及公路线形的制约,跨越沟壑的大跨度斜连续梁桥的修建将非常普遍。然而在山区,受到施工场地和运输条件的限制,顶推施工的方法是大跨度斜连续梁桥建设中非常有竞争力的一种。但是斜连续梁桥的计算理论尚未成熟,且采用顶推施工的斜连续梁桥也比较少,对其关键技术也处于摸索阶段,因此有必要对斜连续梁桥的顶推施工开展系统的研究。
本文的内容是交通部西部课题——大跨度斜连续梁桥顶推新技术与施工控制技术研究(2004BZ11)的一部分。以张家界澧水大桥为工程背景,探讨了斜连续梁桥的受力特点,对顶推施工中的关键工况进行详细的应力分析,本文的主要研究内容有以下几个方面:
(1)本文采用实体建模方法,考虑斜度、预应力和导梁对顶推的影响,编制了基于ANSYS平台斜连续梁桥顶推施工二次开发程序,该程序将ANSYS空间结构分析软件与VC++6.0有机结合,实现了对顶推施工关键工况进行详细的应力分析的功能
(2)运用斜连续梁桥顶推仿真分析二次开发程序,对张家界澧水大桥(8×50m,斜交角70度)顶推施工关键工况——最大负弯矩工况和最大正弯矩工况进行仿真分析,得到两个工况关键截面的详细的应力情况。
(3)张家界澧水大桥为斜连续梁桥,为研究斜连续顶推箱梁桥空间应力,本文先建立了参考文献中的试验模型,将分析结果与试验数据进行对比,验证采用实体有限元法分析空间应力的可行性,然后采用顶推仿真分析二次开发程序建立澧水大桥的平桥、横坡桥、斜桥及三向预应力模型。通过各个参数模型结果对比分析,研究了横坡、斜度、纵向预应力、横向预应力及竖向预应力对箱梁顶板轴向应力分布的影响。
China is very mountainous country, especially in the west district where distribute many ravines. So when built high way in west district for the restrict of terein、physiognomy and geology, construct long-span skew continuous bridges will be very common. However, in the mountainous district, for restricts of construction yard and transport condition, so the incremental launching method is a competitive construction method. But the analysis theory of skew bridge is not mature, the experience of constructing skew bridge with incremental launching method is limit, and the key technology of construction skew bridge with incremental launching method is questing. So it’s necessary to systemic study the construction skew bridge method with incremental launching method.
The content of this paper is a part of the Traffic western issues, which was named the study of long-span skew continuous girder bridges by incremental launching method and construction control technology (2004 BZ11). Using solid modeling methods, a secondary development procedure of skew continuous bridge incremental launching method was programmed based on the ANSYS platform .And it was on the basis of plane procedure ILMP of skew continuous girder bridges construction simulation analysis, and also took the skewness, the prestress and the impact of the nose girder on incremental launching into account. The procedure integrated the ANSYS analysis software of spatial structure and VC++6.0 organically, and it realized the function of detailed analysis of the stress on the key state for incremental launching construction, and also improved the function of the plane procedures ILMP of incremental launching construction simulation analysis.
Using the secondary development of procedures, Zhangjiajie Lishui River Bridge (8×50m, skewness of 70 degrees) was taken simulation and analysis to the largest negative moment condition and the positive moment condition, which is the key state of the incremental launching construction, and the detail conditions of stress can be obtained. Comparing with the measured stress value at the scene, it verified the reliability of the process.
Zhangjiajie Lishui River Bridge is a skew continuous bridge. For study the space stress of the girder, the paper build the test modle, vertified the method feasibility by finit element method to analysis the space stress by compared with the test data. The built the level bridge, skew bridge and three prestressed model of Lishui bridge by second develop procedure. By compared with every parameterize model analysis result, study the affect of the cross slope, skew degree, longitude prestressed, cross prestressed and vertical prestressed to space stress.
