摘要：
Based on the model test result of the obvious effect of prestress on deformation resistance of the reinforced cantilever structure, the prestressed reinforcement technology was applicable to control the differential settlement of the embankment. Comparing the model tests of the embankment without and with reinforcement, and prestressed reinforcement, the influence law of the reinforcement and prestress on the differential settlement of the embankment was studied. The differential settlement of embankment under various working conditions was calculated by the derived prestressed-reinforced-filled three-phase composite vertical modulus. The results show that the application of reinforcement and prestressing can make the vertical composite modulus largely increase the stiffness and integrity of the embankment, the bearing capacity of the embankment is improved by 1-3 times, and also the differential settlement of the embankment reduces by 76% - 88%. © 2020, Central South University Press.
