【摘要】 岩体破坏模型重要影响因素之一是岩体本构模型,邓肯—张模型是岩土工程中应用最为广泛的土的非线性弹性本构模型.本文对邓肯-张非线性弹性模型的影响因素进行了分析,并结合实例说明,本构模型中有关参数的取值和匹配对模型的应用和工程计算均有较大影响.更多还原

【Abstract】 One of the important influencing factors of the model of rock mass destruction is the constitutive model of the rock.Duncan-Zhang model is the most widely used non-linear elastic soil constitutive model in the geotechnical engineering.In this paper,the influencing factors of Duncan-Zhang nonlinear elastic model are analyzed and demonstrated with examples.The values determined and the match of some parameters in the constitutive model have a great impact on the application of the models and engineering calculations.更多还原
