既有提载石拱桥承载能力评定与维护实践

Bearing Capacity Evaluation and Maintain Practice of Existing Lifting Load Stone Arch Bridge

本文以某石拱桥为工程背景,针对该石拱桥特点通过相关检测技术手段、承载能力检算等方法分析,结合整体道路改造工程进行提载承载能力评估,最后结合现场实际情况和检测评估结果提出了该桥维修处理方案及施工要点,并给出后续的养护建议。

In this paper,taking a stone arch bridge as the engineering background,according to the characteristics of the stone arch bridge,through the analysis of relevant detection technology means,bearing capacity calculation and other methods,combined with the overall road reconstruction project,the load-carrying capacity evaluation was carried out.Finally,combined with the actual situation and the detection and evaluation results,the bridge maintenance treatment scheme and construction points are proposed,and the follow-up maintenance suggestions are given.
