Abstract：Inorder to study the bearing capacity and structural safety of anew HD-2OO deck bailey bridge under normaloperating conditions，theload testand finite elementanalysis werecariedout.Thethre-dimensional space grillage modelof Baileybeam bridgeis establishedbyusing thebridge software Midas civil.Basedontheprinciple of the most unfavorable force，the test section and test conditions are determined.By determining the test loading scheme and thearrangementofon-site measuring points，thestatic load testis to test the stressanddisplacementof each section measuring point，and thedynamic load test is to test the frequency，vibration mode and impactcoefficient of Bailey bridge.The measured values and theoretical values are compared and analyzed.The test results show that the Bailey beam bridge is inan elasticdeformationstate asa whole;undertheactionofdynamic load，the natural vibration frequency and impact coeficient of Bailey beam structure are within the allowable range of the code.
