The rationality of bridge static load test results has a great relationship with the static load test method.In view of the shortcomings of the existing static load test,this paper takes the static load test of a continuous beam bridge as the research object to discuss the influence of static load test model correction and beam defect on static load test.The following results are obtained:the numerical model corrected by finite element correction technology is in good agreement with the actual situation;when the compactness of the concrete at the lower edge of the mid span is low,the tensile strength and elastic model of the concrete in this area will be reduced,thus reducing the crack resistance,vertical bending stiffness and prestressing degree of the beam.When the compactness of the concrete at the lower edge of the mid span of the beam is low,the crack resistance and stiffness should be tested by static load test,and the construction must be carried out after ensuring compliance.
