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险相关的风险。需要关注的不仅是我们的城市，还有连接城市中心的基础设施。该提案将涉及两条研究路线：一条是加强我们对路面结构中使用的颗粒材料的力学行为的了解，目的是改进考虑到不断变化的环境条件的设计；另一条是开发分析技术，以更好地处理不稳定性的模拟和预测，特别是更好地模拟泥石流滑坡和山体滑坡，以及沿沿海地区或河流岸线发生的水流滑坡中的土壤-水相互作用。水流滑坡有可能破坏自然的水生栖息地，破坏近海管道和基础设施，并对防洪造成负面影响。碎片和山体滑坡是对我们的交通网络和基础设施的直接威胁。

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.
