Study on Horizontal Displacement of Alluvial Flat Soft Ground under Embankment

Abstract:

There are three soft ground types in the joint highway of Jiaozuo-Gongyi Yellow River bridge in Henan province: shallow, sandwich and deep layers. By analyzing the observation date, the horizontal displacement characteristics of alluvial flat soft ground under embankment are studied. The settlement is the dominant deformation in construction time, but the mainly factor that controls construction speed is horizontal displacement of the weakest layer. The failure mode of sandwich and shallow type grounds is different to the circular one in deep type ground, so the translation mode is put forward. Due to the uniform in thickness and spaces of alluvial flat soft ground, the horizontal displacements are quite different at both sides of subgrade.
