Failure at large scale such as slopes, embankments, and underground mining is fatal in terms of human lives and property loss. This project aims to develop a new methodology to connect micro-mechanisms that trigger and govern failure with the behaviour at much larger scales. In particular it will allow building constitutive models directly from micro-scale mechanisms, while possessing the capability to span the spatial scales. It will also transform the understanding of material property scaling into a predictive tool for engineering analysis, helping to obtain more cost effective designs with greater confidence in safety.

大规模的破坏，如边坡、滑坡和地下采矿，对人类生命和财产的损失是致命的。该项目旨在开发一种新的方法，将触发和管理故障的微观机制与更大规模的行为联系起来。特别是，它将允许直接从微观尺度机制构建本构模型，同时具有跨越空间尺度的能力。它还将把对材料性能缩放的理解转变为工程分析的预测工具，帮助获得更具成本效益的设计，并对安全性更有信心。
