The aim of this project is to develop a robust optimisation technique for identifying geomechanical parameters for subsequent stability analysis of rock structures in particular open pits. The development involves a novel solution method based on current work in finite element method and large-scale optimisation with partial differential equation constraints. The outcomes of the project will provide a sophisticated numerical technique for geotechnical engineers/scientists to determine geomechanical parameters accurately from in-situ observation and displacement measurements, leading to the optimal design of rock structures in subsequent analysis.

该项目的目的是开发一种可靠的优化技术，用于识别地质力学参数，以便对岩石结构特别是开放坑进行稳定性分析。该开发涉及一种基于有限元方法的当前工作和具有部分微分方程约束的大规模优化的新型解决方案方法。该项目的结果将为岩土工程师/科学家提供一项复杂的数值技术，以从原位观察和位移测量中准确地确定地质力学参数，从而在随后的分析中实现岩石结构的最佳设计。
