Abstract

Based on the failure mechanisms analysis of the strengthening method of anchoring assisted steel beams of the existing heavy haul railway concrete simple double-T girders, the plastic ultimate bearing capacity analysis method are presented in this paper, the calculation formula of the strengthening of anchoring assisted steel beams of the concrete simple double-T girders is derived, the ultimate bearing capacity of the heavy-haul railway concrete simple double-T girders is calculated, the field test is carried out to verify the calculation results of theory analysis. The calculation and test results show that the strengthening method of anchoring assisted steel beams can improve the ultimate bearing capacity of the concrete simple double-T girders.
