Abstract


In this thesis, in the context of transportation construction in China cause of the rapid development of road transport substantial growth for the status quo of China 's old bridge , in order to strengthen the conservation of roads and bridges , repair, reinforcement and renovation work to improve Old Bridge carrying capacity and driving performance and extend the service life of the target . The goal of this thesis is to be built in 1968 in Shenyang City the new leather Shen Link Bridge original design vehicle -13 , trailer load of -60 standards to meet cars - 20 , trailer load requirements - 100 . The research method is mainly the bridge static and dynamic load tests and bearing capacity assessment as a basis for guiding the Old Bridge Retrofitting , on this basis, a reasonable Retrofitting , according to Bridge Design Specifications , use of the limited element structural analysis assurance program to meet the requirements of security, economic and other aspects of common procedures and special procedures for reinforced structural capacity analysis checking . Content , in accordance with the load-bearing structure of the bridge superstructure bridge bearing capacity test - bridge carrying capacity analysis and calculation - Reinforcement Countermeasures Analysis - Reinforced Bearing Capacity of steps as well as the introduction and the end of the two parts is divided into six chapters . The significance of this study is : from the microscopic point of view , the above theory, technology absorption , digestion and applied to solve a series of practical problems ; From a macro point of view , these studies , summed up a set of simple, feasible bridge inspection , evaluation, reinforcement , Similarly about to enter and has entered the maintenance of roads and bridges for the conservation and Retrofitting work for our country to provide a technically feasible and economically reasonable good example .
