自锚式悬索桥锚固部位的模型试验研究
|
摘要
本文以成都清水河混凝土自锚式悬索桥为研究背景,该桥为我国西南部第一座自锚式悬索桥,其加劲梁为混凝土结构,锚固区采用钢混组合结构,为了了解其受力特征及传力机理,并为设计和运营维护提供依据,我们针对锚固区部位进行了1:2.5倍的模型试验。
以自锚式悬索桥计算理论、有限元法、相似理论为指导,在总结相关桥梁结构试验方法及成果的基础上,进行了锚固部位的理论分析与模型试验研究。本文展开了以下几个方面的工作:
(1)介绍了自锚式悬索桥的发展历史和国内外的应用现状,总结了自锚式悬索桥的基本构造特点和受力特征,指出了自锚式悬索桥存在问题和发展趋势;
(2)系统总结了自锚式悬索桥采用混凝土加劲梁、钢混组合加劲梁和钢加劲梁时的主缆锚固系统。
(3)根据模型试验的相似理论设计了锚固区部位模型;利用大型有限元分析程序ANSYS建立空间有限元分析模型,确定试验的测点和荷载工况;将各工况下结构控制截面的实际应力同计算值进行比较:检验了锚固部位在最不利设计荷载下的工作状态,验证了钢锚箱与周边混凝土粘结的可靠性,并计算总结出该部位的实际受力规律。
Based on the concrete self-anchored suspension bridge in Chengdu to the background,the bridge is the first self-anchored suspension bridge in southwestern of China,the materal of its stiffening beams is concrete,the anchorage area take steel-concrete composite structure,In order to understand its mechanical characteristics and load transfer mechanism,and provide evidence for the design and operation management,A scale(1:2.5)anchorage model is tested for the anchorage area system design of the Qingshui River self-anchored suspension bridge.
Based on the calculation theory of the self-anchored suspension bridge、finite element method、similitude theory,we summarized the method of the test and achievement of the corresponding bridge structure experiment,we have a research on theory analysis and model experiment of the anchorage area.The practical work is as following:
(1)This thesis introduces phylogeny and application actuality inland and abroad,summarizes the basic construction and forcing characteristic and indicates the existed problems and developing trend of self-anchored suspension bridge.
(2)This thesis summarize the cable anchorage system of self-anchored suspension bridge with the differren material.like the concrete stiffening girder,steel-concrete combination girder,steel stiffening girder.
(3)designed model of the anchorage area according to the similitude theory,under the large-scale finite element analysis program ANSYS,created a model to analysis the stress of the anchorage area,making sure the survey points and load styles,the stress and strain of test were compared to the result of the calculation,verify the working station under the disadvantage design load.validate the reliability of the bond problems of steel-anchor-box and concrete,and summarize the force distribution rule.
