Analysis on Critical Height of Embankment on Natural Soft Foundation

XU Yong-fu

Abstract

According to Boussinnesq stress formula and Mohr-Coulomb failure criterion,the calculation formula of embankment critical height on natural soft foundation is educed.Considering the diffusion of embankment load by surface hard shell,the influence of hard shell thickness and rigidity on embankment critical height is analyzed.The formula of embankment critical height in this paper can be simplified into Babu-Cove Formula and Fenenius Formula under special situations.
