Contemporary geotechnical design often requires the use of advanced numerical analysis, if it is to take account of the complex nature of many geotechnical problems. One crucial aspect of such analyses is the realistic representation of the facets of soil behaviour that are dominant in any given problem, which in turn requires a careful selection of an appropriate constitutive model and derivation of model parameters from the available, and often disparate, experimental data. This paper uses the authors’ experience of advanced numerical analysis and constitutive modelling to emphasise the importance of close integration of the process involved with interpreting experimental data with the process of selecting and calibrating advanced constitutive models, in successfully predicting the response of geotechnical structures.

如果要考虑到许多岩土工程问题的复杂性，当代岩土工程设计通常需要使用高级数值分析。这种分析的一个关键方面是对任何给定问题中占主导地位的土壤行为刻面的真实表示，这反过来又需要仔细选择合适的本构模型，并从可用的，通常是分散的实验中推导模型参数。数据。本文利用作者在高级数值分析和本构模型方面的经验，强调了将解释实验数据的过程与选择和校准高级本构模型的过程紧密集成在一起的重要性，以成功预测岩土结构的响应。
