邓肯-张模型参数敏感性分析

Analysis of Parameters Sensitivity of Duncan-Chang Model

在岩土介质非线性弹性模型的反演分析中,通常采用邓肯-张模型,这一模型中与弹性模量和泊松比有关的参数有8个。如果将这8个参数都进行反演,计算工作量太大,也没有必要。本文主要是对这些参数进行敏感性分析,以减少反演分析的工作量。

When antianalyzing the nonlinear elastic model of geotechnical medium, people usually use DuncanChang model.In this model,there are eight parameters relative to elastic modulus and Poisson ratio.If someone antianalysizes these eight parameters at the same time, working capacity of calculation will be enormous,and the calculation is not necessary.So this paper analyzes the sensitivity of these parameters for antianalysis.
