Abstract: The corrosion drainage pipes with dense pipe bedding, void pipe bedding and polymer repaired pipe bedding were taken as the research object, and the field full-scale test was carried out for corrosion pipes with three different pipe bedding states under different vehicle axle loads. According to the field test, the refined three-dimensional finite element models of corroded drainage pipes with dense, void and polymer repaired pipe beddings were established, respectively, and the reliability of the test results was verified. The results showed that the measured data were in good agreement with the simulation results, and the maximum error was only 10.9%. When the vehicle axle load increased from 15 t to 20 t and 25 t, the strains on the inner wall of the bell and spigot crown of the void pipe were increased by 62%, 54%, 38% and 36%, 14% and 11%, respectively, compared with that of the dense pipe, which indicated that the void pipe bedding could significantly change the stress state of the pipe. The circumferential strains on the inner and outer walls of the bell and spigot of the dense pipe were very close to the repaired pipe, which indicated that the polymer grouting pretreatment technology had a significant effect on repairing the void pipe bedding.
