Research On Disease And Load Test Of New Chengpeng Continuous Beam Cloverleaf Junction

With the rapid development of traffic and the advancement of technology,the detection of bridge is considered to be more and more important.Its main signification expresses in the applications as follows:assess of actual carrying capacity of today’s bridges, foundation of technical information of bridges, and developments of the assess theories of old bridges and design theories of new bridges. However,load test is an important testing method, which can provide advantageous and direct bases for administrators to evaluate carrying capacity of bridge.Especially for the new structure, bridge design theory and working techniques,it can provide valid actual data.The new Peng Cheng continuous beam cloverleaf junction,the content are as follows:Firstlly,the detection methods of the continuous beam bridge are introduced,including general detection and detailed load testingSecondly,the detection result of the bridge is introduced,and it make some analysis from the crack of the bridge to the result of rebound,and analyse the material.Finally,after the analysis of dynmaieal and statical capaeities,the comparison analysis of the actual and theoretical deflection and stress values is conducted in order to calculate the check coefficient to determine the real loading capacity of the bridge.runnning and jumping tests of motor vehicles are conducted in order ti determine the real condition of the bridge under dynamic load.based on the time history curves of the controlling sections of each case,the real impacting factor of the bride is determined.
