This project aims to develop an accurate and efficient simulation framework that allows the consideration of realistic discrete behaviour in geomechanical models without the computational overheads of current models. New computational methods and open-source simulation tools will be developed which will enable the efficient and accurate dynamic simulation of large-scale problems in geomechanics, problems that had formerly been intractable because of their computational size. The unique combination of discrete and continuum methods will allow the economical solution of a range of important geotechnical problems such as the accurate prediction of dynamic effects due to tunnelling, underground workings and mining activities. The outcomes will lead to safer and more economic construction methods and a more accurate assessment of the environmental effects.

该项目旨在开发一个准确和有效的模拟框架，允许考虑地质力学模型中真实的离散行为，而不需要当前模型的计算开销。将开发新的计算方法和开源模拟工具，使之能够高效和准确地动态模拟大规模的地质力学问题，这些问题以前由于计算量大而难以解决。离散和连续方法的独特组合将允许以经济的方式解决一系列重要的岩土问题，例如准确预测隧道开挖、地下施工和采矿活动的动态影响。其结果将导致更安全、更经济的施工方法，以及对环境影响的更准确评估。
