Abstract: Dynamic and static load (DSL) tests provide an important tool for safety inspection of bridge structure.The test results reflect the actual working condition, bearing capacity and working performance of the bridge structure, laying a scientific basis for the operation safety of the bridge.This paper carries out the DSL tests on a rigid-frame bridge, details the loading plans and test process, and analyzes the stress state under static loads and the dynamic properties under dynamic loads.The results show that the bridge belongs to the elastic state under design load, and satisfies the requirements of the design and normal use in terms of bearing capacity, stiffness and working performance.The inspection method and findings of this research provide important references to the DST testing and evaluation of similar bridges.
