项目摘要

The UK's transport infrastructure is one of the most heavily used in the world. The rail network takes 50% more daily traffic than the French network; the M25 between junctions 15 and 14 carries 165000 vehicles daily; London Underground is Europe's largest subway. The performance of these networks is critically dependent on the performance of cutting and embankment slopes which make up £20B of the £60B asset value of major highway infrastructure alone. Many of these slopes are old and suffering high incidents of instability (increasing with time). Our vision is to create a visualised model of transient water movement in infrastructure slopes under a range of current and future environmental scenarios, based on a fundamental understanding of earthwork material and system behaviour, which can be used to create a more reliable, cost effective, safer and more sustainable transport system. The impact of the improved slope management will be highly significant in both direct economic and indirect social and economic terms: planned maintenance costs 10 times less and reduces delays caused by slope failure. This proposal offers a unique opportunity to unite 6 academic institutions and coalesce their field, laboratory and computing facilities; with a large cohort of PhD students and experienced stakeholder community we will undertake world leading science and create a long-term legacy.Individually, the partners in this proposal, in collaboration with key infrastructure owners and engineering companies, have been responsible for the instrumentation of 15 cut slopes and embankments, the development of numerical models which couple hydrological and geotechnical effects, and the development of laboratory and filed testing to provide parameters to populate these models. These studies have helped to define the type of problem that is being faced and begin to understand some of the interactions between weather, soil and vegetation. However, further research is required in order to better understand material behaviour (particularly the composite behaviour of soil, water, air and vegetation); slope system behaviour (particularly the effects of temporal and spatial variations of material properties) and the relationships with environmental effects and engineering performance. Furthermore, the integration of the material and slope behaviour with that of the behaviour of the infrastructure network as a whole has thus far not been possible.It is important for the sustainable management of infrastructure slopes (assessment, planning, repair, maintenance and adaptation) to have models that can assess the likely engineering performance of infrastructure slopes, both now and in the future. Recent model development has started to consider the input of weather patterns, and can therefore model the potential effects of future climate. However it has become clear that these models are sensitive to the way in which a number of the physical processes and properties are incorporated, many of which are complex and difficult to quantify directly. A better understanding of the interactions between earthworks, vegetation and climate is required to formulate robust guidance on which maintenance approaches should be adopted and how they should be applied. iSMART will use a combination of field measurements, lab testing and development of conceptual and numerical models to investigate the uncertainties and knowledge gaps enumerated above and to visualise the complex interactions taking place over time and space. This knowledge will help the managers of the UK's transport infrastructure to identify problem sites, plan and prioritise maintenance activity, and develop assessment and adaptation strategies to ensure future safety and resilience of geotechnical transport infrastructure.

英国的运输基础设施是世界上使用最多的运输基础设施之一。与法国网络相比，铁路网络的日常流量要多50％。每天15至14辆车之间的M25；伦敦地下是欧洲最大的地铁。这些网络的性能至关取决于切割和路堤插槽的性能，而切割和路堤插槽的性能仅占主要高速公路基础架构的60b£60b资产价值的20B英镑。这些插槽中有许多是古老的，并且遭受了不稳定的高事件（随着时间的推移而增加）。我们的愿景是基于对土方材料和系统行为的基本了解，在当前和未来的环境场景中创建一个可视化的基础设施插槽中的瞬态水运动模型，该模型可用于创建更可靠，更具成本效益，更安全，更可持续的运输系统。在直接经济和间接的社会和经济方面，改进的坡度管理的影响将非常重要：计划的维护成本降低了10倍，并减少了由于坡度故障而造成的延迟。该提案提供了一个独特的机会，可以团结6个学术机构并结合其领域，实验室和计算设施； with a large cohort of PhD students and experienced stakeholder community we will undertake world leading science and create a long-term legacy.Individually, the partners in this proposal, in collaboration with key infrastructure owners and engineering companies, have been responsible for the instrumentation of 15 cut slots and embankments, the development of numerical models which couple hydrologic and geotechnical effects, and the development of laboratory and filed testing to provide parameters to populate these型号。这些研究有助于定义面临的问题类型，并开始理解天气，土壤和植被之间的某些相互作用。但是，为了更好地理解材料行为（尤其是土壤，水，空气和植被的综合行为），需要进一步研究。坡度系统行为（尤其是材料特性的临时和空间变化的影响）以及与环境效应和工程性能的关系。此外，到目前为止，材料和斜率行为与基础设施网络的行为的整合是不可能的。对于可以评估基础架构插槽的可持续管理（评估，计划，维修，维护和适应性）对于可以评估基础结构工程性能的模型以及现在以及未来的基础结构的可能性。最近的模型开发已经开始考虑天气模式的输入，因此可以对未来气候的潜在影响进行建模。但是，很明显，这些模型对许多物理过程和属性的合并方式很敏感，其中许多模型很复杂且难以直接量化。需要更好地理解土方工程，植被和气候之间的相互作用，以制定强大的指导，以便采用维护方法以及如何应用它们。 ISMART将结合现场测量，实验室测试和概念和数值模型的开发来研究上述列举的不确定性和知识差距，并可视化随时间和空间随时间和空间发生的复杂相互作用。这些知识将帮助英国运输基础设施的经理确定问题站点，计划和优先考虑维护活动，以及开发评估和适应策略，以确保岩土技术运输基础设施的未来安全和弹性。
