大跨度曲线刚构桥静力特性研究
|
摘要
近年来,曲线桥在我国得到了蓬勃的发展,也取得了不少的成绩。随着我国交通事业的迅速发展,高等级公路开始进入西南山区及深沟地区,跨越深、宽沟桥梁会越来越多。在这一地区修建桥梁特别是高等级公路上的桥梁,主要特点是高墩弯桥,曲线刚构桥应运而生。
本文主要内容如下:
(1)总结了曲线桥的发展历史与现状,介绍了曲线刚构桥在我国的建设情况。
(2)介绍了曲线刚构桥常用的分析理论及微分方程。
(3)以泥溪沟大桥为背景,仅改变其曲率半径,进行有限元建模。
(4)运用有限元软件,分别计算了五种不同曲率半径的刚构桥在施工阶段自重作用下及营运阶段活载作用下的内力和变形,得出了曲率半径并不改变受力最不利位置,也不改变挠度最大值位置的规律。
(5)通过对不同曲率半径下悬臂施工及营运阶段的不同荷载工况进行分析,得到不同曲率半径下自重、活载、温度等参数对曲线刚构桥内力及变形的影响规律,为曲线刚构桥的优化设计提供理论依据。
In recent years, curved bridge in China has made a large development, and also made a lot of efforts. With the rapid development of China's transport,. high-grade highways entered the Southwest mountain areas and deep trench region, more and more bridges will across them. The bridges in this region, especially when the bridge on the highway, the main features are high piers and curved beams, so curve rigid frame bridge came into being.
This papers contains as follows:
(1) Summarizes the history of the development curve bridges and the actual state, and introduced the curve rigid frame bridge in our country's development.
(2) Describes the commonly used theory incurved rigid frame bridges and differential equations.
(3) On the background of Ni Xigou Bridge, only change its radius of curvature in the finite element modeling.
(4) By using the finite element software calculate five different radius of curvature of the rigid frame bridge under gravity during the construction phase and operation phase of the internal force under the action of live load and deformation. Reached the radius of curvature does not change the force of the most disadvantaged position, nor to change the laws of the location of the maximum deflection.
(5) Through the different radius of curvature of cantilever construction and operation of the next phase of the analysis of different load conditions obtained under the weight of different radius of curvature, live load, temperature and other parameters on the curve of rigid frame bridge with the impact of internal forces and deformation laws for the curve just Optimal design of the bridge structure provides a theoretical basis.
