Study On Reinforcing Technology Of Qili River Bridge In Xingtai City

With the continuous development of China's national economy, the transport volume increased substantially, bridge load-increasing part of the original bridge aging, damaged, can no longer meet the requirements of modern transport, there is an urgent need to be technological transformation. There are plans, steps to strengthen the existing bridge will conduct surveys and analysis of the damaged reasons, and to take corresponding measures on the existing reinforcement of the old bridge to enable them to meet the new era of highway transportation needs can be better ways to build the bridges reinforced or modified technology we can bring enormous economic and social benefits.This degree thesis against Xingtai– Zuoquan highway Qilihe River Bridge in Xingtai City, the capacity to experiment, according Before the reinforcement and strengthening of the review prior to loading test results bridge reinforcement programs, and programs aimed at strengthening control of points. Before the reinforcement of the measured dataa nd reinforcement of the hierarchy of test data were compared to detect more ideal reinforcement effect.Qilihe River Bridge in Xingtai City,has been left by construction design program, and have achieved good results. After the reinforcement of both strength and stiffness are greatly improved, the bridge carrying capacity of the bridge to the original Steam motorcycle-20, Trailers-100 linked to a new level of standards Highway 1 level, and a certain degree of resistance reserves. Meanwhile, preliminary tests reflects the reinforcement of the structure with the mother of the distribution mechanism, thus reinforcing effect is obvious that successful.
