从广义位势理论的角度看土的本构理论的研究

Constitutive theory of soils based on the generalized potential theory

本文介绍了广义位势理论的基本思想,并从广义位势理论角度出发剖析传统本构理论在表述土的本构关系的局限性。分析了从广义位势理论出发来建立土的本构模型的优点,其可以突破传统理论中以塑性公设为前提的限制,因而,从广义位势理论角度上来建立土的本构模型的具有更广阔的前景。

The concept of generalized potential theory was briefly introduced. Based on the generalized potential theory, the limitation of traditional constitutive theory in expressing the constitutive relation of soils was analyzed, and the advantage of the generalized potential theory in establishing the constitutive model for soils was pointed out. It was shown that the generalized potential theory could break the limitation of the plastic postulate which was the base of the classical elasto-plastic constitutive theory, and the constitutive model based on the generalized potential theory would be used extensively.
