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稳健的优化技术，用于识别地质力学参数，以便随后对岩石结构（特别是露天矿）进行稳定性分析。发展涉及到一种新的解决方法，目前的工作的基础上，有限元法和大规模优化偏微分方程的约束。该项目的成果将为岩土工程师/科学家提供一种复杂的数值技术，以便从现场观察和位移测量中准确确定地质力学参数，从而在随后的分析中优化岩石结构的设计。
