| 摘 要： | 多重势面理论给岩土材料的本构关系研究指出了更开阔的数学背景，由此建立的土的本构模型可以无需推求塑性势函数和屈服函数， 且其所能表述的本构关系比通常的塑性位势理论更为广泛。文中介绍了基于多重势面理论所建立的应变空间的多重势面模型，并对其适用性进行验证。

| Abstract: | Multi potential surface theory is essentially a mathematic approach to study the constitutive relation of soils.The model based on multi potential surface theory has wider adaptability than those based on conventional plastic potential theory, and needs no plastic potential functions or yield functions. The multi potential surface model in strain space based on multi potential surface theory is described and verified in the paper. |
