Evaluation of bearing capacity of reinforced concrete box ribbed arch bridge based on static load test

摘要

In order to evaluate the stress and working performance of a reinforced concrete box-ribbed arch bridge after completion, the load test of the bridge is carried out. Static load test is to test the stress and displacement of each section of arch rib under the action of partial load and medium load. Through the experiment with the key parts of the stress (strain) and displacement load and other important data, through analysis and study, the comprehensive analysis of the phenomenon of calculation and test, a comprehensive performance evaluation structure and function whether meet the design requirements, to provide technical basis for the safety of the bridge operation, and provide the original material for the bridge maintenance and management in the future.
