Deformation Properties Analysis of Widen High Embankment on Soft Ground

摘要：

When the high embankment are widen on the soft ground,its inner strain and deformation will be more complicated.Considering the Hejiaping link line widen project in Shanghai-Chengdu Expressway West,applying the Sigma/M model of special software GeoStudio established a two dimension finite elementmodel,applying the equivalent line elasticity theory simulated the deformation properties of the widen project of the high embankment on soft ground.R shows that with the increases of elasticity modulus of soft soil embankment and the new embankment,the greatest settlement of embankment reduces distinctly.If the elasticity modulus of soft soil embankment is greater than 20Mpa and its ratio of the new and old embankment is bigger than 1 ,the impact is not distinct.Laying the geogrid on the new embankment can reduce the lateral deformation of the embankment as well as the settlement difference between the old and new embankments.
