Mathematic model for calculating pre-consolidation pressure based on fragmented curve-fitting

JIN Yaohua;Lü Fanren;SHAO Hongcai;Department of Civil Engineering,Yangzhou Polytehnic College;  
In order to the shortcomings of calculating pre-consolidation pressure by using the single function to fit the e-lgp curve,a mathematical model for pre-consolidation pressure based on fragmented curve-fitting was proposed.According to the least square method,the quartic polynomial and line fitting use of piecewise fitting curve segment and line segment of e-lgp curve,and calculated with the compute program complier by Matlab.Results prove the proposed method is reliable,convenient and practical,which can be taken as a reference for engineering applications.
