Centrifuge Model Test and Numerical Analysis of Embankment Widening on Soft Ground

摘要

Widening of expressways on soft ground induces many embankment and pavement distresses. In this study, centrifuge model tests and numerical analyses (such as finite element analysis) have been carried out for a widening project. Comparison is made between test data and calculated results. The development of settlement, horizontal displacement and pore water pressure in widening are investigated. At the same time, in the centrifuge model test the limit status and failure mechanism of widening is discussed and analyzed.
