The post-construction settlement prediction of the surcharge preloading embankment on soft ground

ZHOU Gang, CHEN Qian-ying, ZHOU Yi-qin ,LING Tian-qing (Tongji University, Shanghai200092, China; Chongqing Communications Research & design Institute, Chongqing 400067, China; Wenzhou Expressway Project Construction Headquarters,Zhejiang Wenzhou 325000, China; Chongqing Jiaotong University,Chongqing 400074,China)  
The experience method, such as the hyperbola method,which is often used in the engineering of highway embankment on soft ground, is incompetent for considering the influence of the variation of preload, so it can't predict the post - construction settlement of the surcharge preloading embankment well. By back - analysing the settlement of an surcharge preloading embankment, this paper fistly get the coefficient of settlement and the average coefficient of consolidation.Then utilizing these coefficients as calculation parameters and taking the influence of the surcharge preload into account, this paper predict the post - construction settlement of an surcharge preloading embankment approxiniatively. For considering the influence of the surcharge preload, the result of this method is more coincident with the fact than that of the hyperbola method and other experience methods.
