抽象的。在英国，未分类道路占道路网的60%.这一对当地很重要的网络的复原力正在下降。它被土木工程师协会认为是“处于危险之中”，在世界上排名第26位。许多因素导致特定路段的退化和最终失效。然而，一些英国地方当局已经确定，在干旱条件下，与非敏感土壤上的路段相比，建立在收缩膨胀敏感粘土上的路段会发生显著恶化。这是因为当地的公路网几乎没有结构基础。因此，东安格利亚的干旱造成了数百万英镑的损失，导致当局寻求紧急政府资金。本文评估了使用土壤相关的地质灾害评估提供土壤知情的维护策略，为资产管理的当地重要的道路网络的英国。一个案例研究借鉴了英国林肯郡的行政县，在那里的道路评估数据进行了分析映射粘土沉降风险。这揭示了一个统计学显着的道路条件和敏感的粘土之间的关系。此外，纳入UKCP 09未来气候预测的地质灾害模型中，突出了道路可能在未来的风险粘土相关的沉降。
Abstract. Unclassified roads comprise 60 % of the road network in the United Kingdom (UK). The resilience of this locally important network is declining. It is considered by the Institution of Civil Engineers to be "at risk" and is ranked 26th in the world. Many factors contribute to the degradation and ultimate failure of particular road sections. However, several UK local authorities have identified that in drought conditions, road sections founded upon shrink–swell susceptible clay soils undergo significant deterioration compared with sections on non-susceptible soils. This arises from the local road network having little, if any, structural foundations. Consequently, droughts in East Anglia have resulted in millions of pounds of damage, leading authorities to seek emergency governmental funding. This paper assesses the use of soil-related geohazard assessments in providing soil-informed maintenance strategies for the asset management of the locally important road network of the UK. A case study draws upon the UK administrative county of Lincolnshire, where road assessment data have been analysed against mapped clay-subsidence risk. This reveals a statistically significant relationship between road condition and susceptible clay soils. Furthermore, incorporation of UKCP09 future climate projections within the geohazard models has highlighted roads likely to be at future risk of clay-related subsidence.
