ACHILLES: reducing earthworks failure risks and whole-life costs
ACHILLES: reducing earthworks failure risks and whole-life costs
Vital transport and other linear infrastructure in Britain and elsewhere depends upon an extensive set of earthworks of varying age, condition and engineering quality. These earthworks are subject to normal deterioration, and these processes are exacerbated and complicated by the variable and unpredictable effects of climate change on weather patterns, particularly in the form of increased rainfall intensity and flooding. Railway earthworks are particularly vulnerable to these effects, given their typical age and the comparatively primitive engineering techniques used in their design and construction, as well as the increasing (pre-Covid) traffic levels to which they have been subjected. This paper describes research work being undertaken to improve the understanding of earthworks condition, deterioration and remediation, and to develop methods and tools to assist with the economic assessment of, selection from and prioritisation of alternative design interventions.

Abstract
Vital transport and other linear infrastructure in Britain and elsewhere depends upon an extensive set of earthworks of varying age, condition and engineering quality. These earthworks are subject to normal deterioration, and these processes are exacerbated and complicated by the variable and unpredictable effects of climate change on weather patterns, particularly in the form of increased rainfall intensity and flooding. Railway earthworks are particularly vulnerable to these effects, given their typical age and the comparatively primitive engineering techniques used in their design and construction, as well as the increasing (pre-Covid) traffic levels to which they have been subjected. This paper describes research work being undertaken to improve the understanding of earthworks condition, deterioration and remediation, and to develop methods and tools to assist with the economic assessment of, selection from and prioritisation of alternative design interventions.
