摘要
桥梁结构由于先天或后天的原因或多或少都存在缺陷或损伤。本文作者研究石砌拱桥出现的裂缝、变形以及其它破坏形式,并充分考虑诸如周边环境、材料抵抗强度等因素对拱桥的影响,引入旧桥检算系数Z,对拱桥的剩余承载能力进行理论分析。
There are some shortages or damages in bridge structures because of the innate or postnatal reasons. In this paper, the cracks, distortions and some other damages of the stone arch bridges are studied, the influence of the surroundings and intensity of materials on the arch bridges are considered and the test coefficient Z of the old bridges is used for theoretical analysis of the residual loading capacity of the arch bridges.
