The Research On Simulation Assessment And Reinforcement Technique Of The Existing Bridges

Increasing with the service time of large number of bridges, assessing and reinforcing of bridge became increasingly to be important part of maintaining of existing bridge. So, we need to evaluate the existing bridges periodical and perennial which are in the service and maintain the defect of them in time to enhance their life-span and performance at the same time of building new bridges. Systemic and embedded academic research and technical exploitation which aim at evaluation and reinforcement technique of national existing bridges have not only fairish academic signification but also important applied value.The thesis is the assessing and reinforcement summary and research result of the two existing bridge, Du Jiangyan Annan Bridge and Shifang Majin Bridge. It introduced in detail the process, the principle, and the method of the assessing analysis of the two existing bridges.it also narrated the reinforcing design and the construction keys after assessing of Shifang Majin Bridge. The correctness, the reasonability and the need for reinforcing design have been proved by the load test. Assessing and reinforcement technique of the existing bridge and the load test which carried out after reinforcing introduced in the thesis can be used for reference and applied in other similar projects on assessing and reinforcing of bridges.
