Model Test and Theoretical Analysis of New and Old Embankments Differential Settlement Considering Lateral Deformation

In the embankment widening project, new will produce large deformation due to low degree of consolidation, which affect stability embankment. Obtaining settlement law is premise ensure this paper, studied through model test, and calculation method proposed. The test results show that old embankments have a difference during loading process, maximum twice lateral directly proportional vertical deformation, sliding occurs under ultimate load, bearing capacity lost. Based on one-dimensional method, coefficient introduced, two-dimensional formula obtained. meshed, each node calculated by formula, between data 6.2%, proves feasibility accuracy method.
