基于ABAQUS对D-P准则剪胀角的讨论
ABAQUS based discussion on dilatancy angle of D-P criterion
摘要
Abstract
In order to describe the strength properties of geotechnical materials properly, the D - P criteria is come out on the basis of the M - C criteria, which is widely used in ABAQUS. However, if the parameters of D - P criteria are improperly selected, larger errors may occur from the calculation results. Therefore, the basic characteristics of the D - P criteria is analyzed herein, and then the non-associated flow rule based matching formula between D - P yield criteria and M - C yield criteria under the condition of plane strain is given. Thereby, the values between 0 and Φ of dilatancy angle can be obtained, and subsequently, the effect of dilatancy angle on dam-foundation system is studied as well.关键词
