Study of Influence Factors of Lateral Deformation of Soft Soil Foundation under Embankments

The lateral displacements developed in soft soil foundations under embankments were studied,because it can be considered a good indicator of the stability and influence the prediction of settlements during and after the construction of embankments.There are some main influence factors,which are the manners of improvement of foundation,soil layer structure,soft soil depth and embankment height.The characters of lateral deformation of soft soil foundation are analyzed when those four factors are changed independently.Some indexes are compared and studied,such as the curve configuration of lateral deformation of foundation and time and depth,the magnitude of lateral deformation,the position of the maximum lateral deformation and the convergence speed of lateral deformation at certain location in the foundation,and some area conclusions are gained.
