报告二：优化理论在岩土工程中的实践

报告人：尹振宇，香港理工大学土木与环境工程系教授

Abstract:In recent decades, various advanced constitutive models for soils have sprung up. The identification of parameters and selection of constitutive models have become one of the hotspots and difficulties in geotechnical engineering, even the engineers are at a loss. Therefore, the purpose of this presentation is to deal with how to intelligently identify models and their parameters, and how to apply them to engineering practice. To this end, the presentation first systematically introduces the basic principles and application fields of various optimization algorithms, and then presents how to improve the performance of optimization-based parameter identification taking the genetic algorithm and differential evolution algorithm as examples. Several typical geotechnical problems are selected to illustrate the practice of optimization theory, such as: (1) the development of empirical correlations for key mechanical parameters of soils; (2) the parameter identification of soils for a given constitutive model; (3) selection of constitutive models for given experimental data; (4) constitutive model selecting and updating during an excavation project.
