Automatic Finite Element Modelling and Parameter Determination for Geotechnical Design

Abstract

This article describes how efficiency in geotechnical engineering involving finite element (FE) modelling can be improved by automation. An important part of geotechnical FE modelling involves the creation of an underground model and the determination of soil and model parameters. It is explained how Automated Parameter Determination (APD) based on CPT data can be used in conjunction with geological modelling to create the necessary input for a FE model. An example demonstrates the entire workflow. The system is transparent and extendable. It supports the geotechnical engineer in the complex task of parameter determination, while retaining the responsibility at the user. Automation can help reducing the spread in results when different geotechnical engineers analyze the same problem, and hence, it can contribute to the confidence in the use of advanced numerical methods for geotechnical design.
