Abstract:: Polymer grouting technology was a kind of economical and efficient method for leakage of pipeline. However, the application of this technology for the restore statue of the mechancial properties of the pipe afer repairing was not yet clear.In this paper, the three-dimensional numerical model of the road structure,subgrade and pipe-soil interaction were established by the ABAQUS software.The longitudinal and circumferential mechanical properties of normal pipes, disengaging pipe and polymer-repaired pipe under traffic load were compared and analyzed. The results showed traffic load had obvious influence on the pipe stresses and deformations in the range of 6m and 4m on both sides of its position, and the influence was positively correlated with the amplitude of traffic load.The stresses at the bell and spigot joints were highly discontinous.When traffic load was 1.0MPa, the stresses and deformations of the pipe are obviously greater than that of traffic load is 0.5MPa;The stresses and deformations of the pipe recovered to the normal pipe level after the disengaging was repaired by the polymer, and a reliable and effective repairing effect was achieved.The research results provided a theoretical basis for the implementation of targeted pipe repair.
