Abstract

In the paper, we combined with an actual engineering about an old bridge which filling pile. Through conducting the structure performance testing and cap beam Carrying Capacity of the old bridge, and using the comprehensive assessment method grading the old bridge, these provide a scientific basis for the old bridge reinforcement in the future. The analysis results showed that, the bridge site conditions in which poor, severely damaged steel and concrete structures, poor structural performance, Carrying Capacity of the main members does not meet the requirements of the highway bridge load rating at the present stage, the rating is four.When the live load is arranged along the bridge, take the continuous two-span along the bridge, the live load bearing reaction force of the maximum separately were calculated, which under the action of car -20, trailer-100 and the crowd load and with single span and double span arrangement.This bridge belongs to comprehensive assessment method in the fourth type bridge, there is a big security risk, must reinforced timely.
