斜靠式拱桥稳定性分析
Stability analysis of double X - shape arch bridge
【摘要】 以平顶山市城东河路湛河桥主桥——斜靠式拱桥为研究对象,采用Midas/civil有限元程序.建立了该 拱桥的空间有限元计算模型,分4种工况计算了该桥的稳定安全系数,并对桥梁的失稳特征进行了分析. 本文计算结果对了解该桥及同类斜靠式拱桥的稳定性具有较大的参考价值.
【Abstract】 The main bridge of Zhanhe River located in Pingdingshang is double X - shape arch bridge. For this research object, adopting midas/civil finite element procedure, the author set up the space fir ite element calculating model of the arch bridge, divided into 4 operating mode to calculate steady safety factor of the bridge, and analyzed the stability. The result of this paper is of referenced value in learning about the stability of this bridge and other similar double X - shape arch bridges.
