Research on the Post-Evaluation Method for Common Highway Bridge Strengthening

摘要

For the common highway bridge strengthening works, this article divides the evaluation of bridge strengthening works into three categories layers - durability, safety and suitability, to evaluate the bridge strengthening from a technical level. Then analyzed separately for each category layer, select the parameter indices which have an important influence on each category layer to be the evaluation indicators. When evaluating the safety and suitability, the durability has been taken into consideration to amend their evaluation scores. On the basis of the obtained scores of the category layers, by using the Analytic Hierarchy Process method and the weighted average method, we can get the evaluate score of the members, components, parts entirety and the entirety of bridge successively. Proposed a kind of post-evaluation method applies to the common highway bridge reinforcement. This post-evaluation method provides theoretical references for the effect post-evaluation bridge reinforcement.
