Abstract

Abstract: Based on the study on the lateral stability of the deek-type and bottom-road arch bridge,a practical formula to deter-mine the critieal load of the lateral stability of the midheight-deck arch bridge is given.

Key words: midheight-deck arch, lateral stability, critical load

摘要： 本文在已有对上承式与下承式拱桥稳定性研究基础上，利用能量原理方法提出了中承式拱桥在使用阶段的横向整体失稳临界荷载实用计算式，并分析了行车道梁立面位置对其稳定性的影响。
