摘要
为了评定旧混凝土拱桥的承载能力,通过结构混凝土强度、保护层厚度和碳化深度综合确定承载能力检算系数和截面折减系数,根据通行状况确定荷载效应组合,分别在承载能力极限状态和正常使用极限状态下进行检算,实现旧混凝土拱桥的承载能力评价。
In order to accurately assess carrying capacity of the old concrete arch bridge, through the integrated structure of concrete strength, the thickness of the protective layer and carbonation depth to determine the bearing capacity coefficient and cross section reduction factor, combination of action effects is determine reasonably,structure calculations is is checked respectively under the bearing capacity limit state and normal use limit state, evaluation of carrying capacity of old concrete arch bridge is achieved.
