| Abstract: | Based on the widening engineering along Shenzhen Shuiguan Highway, the differential settlement between the new and existing subgrade there was simulated and analyzed with finite element software ABAQUS, as well as the deformation characteristics and the change of stress and pore pressure of the widened subgrade in the course of construction and the operation after construction were studied, which reveals the law and mechanism of widened subgrades differential settlement. |
