对邓肯模型参数敏感性的讨论

Discussion on Parameter Sensitivity of Duncan Model

敏感性分析是目前结构分析计算中解决多参数辩识问题的主要方法。文中以能较好模拟土体非线性力学行为的Duncan-ChangE-B模型为基础,通过算例分析认为Duncan模型参数对位移的敏感性除了有几何效应外,还受到荷载效应的影响和自身取值效应的影响。

The analyses on sensitivity of model's parameters has been recognized as a main method in the analysis of structure constructionIn this paper,the DuncanChang EB model was used to stimulate the nonlinear mechanical behavior of soilApplication in an example show that the on sensitivity Duncan model's parameters is influenced not only by position,but also by load and self values
