Analysis on Settlement of High Embankment Filled with Saturated Loess in an Expressway
Based on a highway filling,the whole process of settlement observation was carried out,and the observed data were analyzed by both hyperbolic and Hoshino curve methods to predict the settlement trend.The result shows that,since the saturated loess foundation is constructed of undercompacted soil,the settlement of high embankment is larger during the rapid filling period and smaller during the resting period.Normally,the primary consolidation deformation takes place on the foundation,while the secondary consolidation deformation is rare;when the empirical coefficient method is used to calculate the final settlement,the correction coefficient of geological factors needs to be adjusted.
