Abstract

Abstract

The theory lags far behind the engineering practice,though the composite ground under flexible foundation has been widely applied to several engineering fields,such as embankments of highway and railway,dams,tailing dams,stack yards.Combined with the present situation analysis of analytical method,the settlement characteristics of the composite ground under flexible foundation was summarized firstly.Then,a simplified analytical solution was presented briefly.The fellowing verification by an engineering case indicates that the solution can more accurately reflect the working behavior of the composite ground under a flexible foundation.And then,on a basis of a standard example,the relationships among eight influence factors and the height of the equal settlement plane,the depth of the neutral point,the stab deformation,the settlement of pile and soil etc.were studied through the solution.It can be concluded that the factors of the four components of the system can all affect the settlement characteristics more or less.It is necessary to pay more attention to the composite ground under flexible foundation based on super-sub structure interaction.
