The improved foundation modulus for the use of Winkler foundation

An improved calculating method for the foundation modulus of Winkler foundation is presented in this paper. The calculating results of foundation modulus respectively from Biot's and Vesic's model are different greatly through the analysis to the two methods. The matrix of using functions of buildings to site types is established and seven conditions are gotten. A new method to calculate the foundation modulus is put forward for different conditions.
