Modelling of Deformation and Instability in Geomechanics

该提案的基本主题是可持续性和管理与潜在危害有关的风险。 不仅我们的城市需要关注，而且连接城市中心的基础设施也需要关注。该建议将涉及两个研究领域：一个是加强我们对路面结构中使用的粒状材料的机械性能的了解，目的是改进设计，考虑到不断变化的环境条件;第二是发展分析技术，以便更好地处理不稳定性的建模和预测，特别是更好地建模泥石流和滑坡，以及发生在沿着地区或河流海岸线的水流滑坡中的土壤-水相互作用。滑坡有可能破坏自然水生栖息地，损坏海上管道和基础设施，并对防洪产生负面影响。泥石流和山体滑坡直接威胁到我们的交通网络和基础设施。

The underlying theme of the proposal is sustainability and managing risk associated with potential hazards. It is not only our cities that require attention but also the infrastructure joining the urban centers. The proposal will address two lines of research: one dealing with enhancing our understanding of the mechanical behaviour of granular materials used in pavement structures with the purpose of improving design that takes into account changing environmental conditions; and the second is to develop the analytical technology to better deal with the modelling and prediction of instabilities, in particular to better model debris slides and landslides, as well as the soil-water interaction in flow slides that occur along coastal areas or river shorelines. Flow slides have the potential to destroy natural aquatic habitats, damage offshore pipelines and infrastructure and negatively impact flood defenses. Debris and landslides are a direct threat to our transportation network and infrastructure.
