	<span style=\"line-height:1.5;\">单柱墩桥梁由于桥墩结构轻盈、占地面积较少，常设置在上跨道路和互通匝道处。近年来我国发生了多起桥梁倾覆事故，倾覆桥梁中单柱墩桥梁占一定比例。本文针对路线纵坡这一影响桥梁抗倾覆的因素，研究其对单柱墩桥梁抗倾覆稳定性的影响规律，提出在条件允许的情况下针对本研究对象桥梁应设置小于2.9%路线纵坡，尽量避免桥梁倾覆。<br />
Bridge with a single pier is often installed on the overpass road and interworking ramp because of its light structure and small area. In recent years, there are many bridge overturning accidents in our country. In this paper, the effect of the route longitudinal slope on the anti-overturning stability of the bridge is studied, and less than 2.9% route longitudinal slope should be set if conditions permit, to avoid the overturning of the bridge as far as possible.</span><span style=\"line-height:1.5;\"></span>
