Study on the Difference between Multipotiential Surface Model and Duncan-Chang Model Based on the Triaxial Test of Heda Highway Turfy Soil

Abstract

Firstly, this paper determined the experiment parameter of Duncan-Chang model, through Heda highway turfy soil ordinary triaxial test. Then get to the elastics strain relationship of the multipotiential surface model according to the data above. And finally get the applicable category of the two model through the contrast of the relationship of body strain and axial strain and the relationship of partial stress and axial strain.
