近年来在岩土工程中提出了不少的土的本构模型。其中帽盖塑性模型在岩土工程有限元分析中应用最广。从理论上讲、帽盖模型特别适用于土,因为它可以考虑应力历史、应力路径、剪胀以及中主应力。但是,现在许多岩土工程人员尚不熟悉确定该模型材料参数的过程。本文提出一个简单可靠的方法,它将帽盖模型的参数与常用的土工试验资料联系起来。 In recent years, many soil constitutive models have been proposed in geotechnical engineering. The plastic model of the cap is the most widely used in geotechnical finite element analysis. In theory, the cap model is particularly suitable for soil because it considers the history of stress, stress paths, dilatancy, and intermediate principal stress. However, many geotechnical engineers are not yet familiar with the process of determining the material parameters of the model. This paper presents a simple and reliable method that relates the parameters of the cap model to commonly used geotechnical test data.
