Abstract

Taking the reinforced concrete tie arch bridge with single span 35m as the engineering background, the load test method of bridge-1 (JTG/TJ 21-01-2015). Load test includes static load test and dynamic load test. By applying the test load equivalent to the design load to the bridge structure, grasp the actual working state of the bridge structure under the test load. By building a finite element calculation model using the large finite element calculation software MIDAS CIVIL, Accumulated the computational experience of the similar bridge type. In the static load test, three control sections are selected to test the deflection of stress (strain) and arch rib L/4 section, vault section, beam L/4 section, and middle section of beam span under forward load and partial load conditions. The check coefficient and relative residual deformation (strain) are calculated according to the test data. In the dynamic load test, the impact coefficient of the vault section under different speeds of the loading vehicle is divided into barrier-free driving and obstacle driving. In the absence of no traffic load on the bridge deck and no regular vibration source, the wind load, ground pulsation and water flow near the bridge site are measured. The used microamplitude vibrations to identify the structural autovibration characteristic parameters.
