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

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.
