中小桥梁狭小空间下橡胶支座更换技术决策体系研究与应用

Research and Application of Technical Decision System for Rubber Bearing Replacement in Small and Medium Bridges in Narrow Space

不同的桥型和不同的支撑体系,将来面临的支座更换作业环境条件可能不一样,这有可能会影响后期橡胶支座更换方法的选择,本文在总结中小桥梁狭小空间更换方法即增设牛腿法、体外支撑法、局部凿除盖梁法优缺点和适用条件的基础上,研究了中小桥梁狭小空间下橡胶支座更换方法决策体系,并进行了实体工程应用,以期为类似工程提供参考。

Different bridge types and different support systems may face different bearing replacement operating environmental conditions in the future,which may affect the choice of later rubber bearing replacement methods.This article summarizes the replacement method of small and medium-sized bridges,which is to add On the basis of the advantages and disadvantages and applicable conditions of the corbel method,external support method,and partial chipping of the capping beam method,the decision-making system for the replacement method of rubber bearings in the narrow space of small and medium bridges was studied,and the physical engineering application was carried out in order to provide similar projects.reference.
