Excavated openings such as tunnels and galleries play a key role in mining and civil infrastructure. This project will develop new solutions for predicting the stability of these openings in soil and rock, and will include the effects of anisotropy, fissuring, and inhomogeneity in both two and three dimensions. It will also study the interaction effects between adjacent openings, as well as the influence of different types of loading and boundary conditions. Where possible, the solutions will be presented in the form of dimensionless design charts for use by practising engineers. The outcomes of the project will lead to safer and more cost-effective designs for a wide variety of underground infrastructure

隧道和廊道等开挖开口在采矿和民用基础设施中发挥着关键作用。该项目将开发新的解决方案，用于预测土壤和岩石中这些开口的稳定性，并将包括二维和三维的各向异性，裂缝和不均匀性的影响。它还将研究相邻开口之间的相互作用效应，以及不同类型的载荷和边界条件的影响。在可能的情况下，解决方案将以无量纲设计图表的形式呈现，供执业工程师使用。该项目的成果将为各种地下基础设施带来更安全和更具成本效益的设计
