Multirisk Landslide Scenarios in Geotechnical Sustainability: A Case Study
Landslide hazards often occur in succession, with slides, rock falls, and debris flows occurring either sequentially or concurrently. Some hazards may be strongly correlated. For example, rockfall is considered as one of the landslide processes, and its deposit forms the source material for subsequent debris flows. This paper aims to present (1) a specific case study of cascading landslide hazards along a highway, (2) the consequences caused by these landslide hazards, and (3) the needs for a multirisk approach to coping with such cascading hazards in engineering planning and design. The case study shows that the assessment of landslide risk in sustainable engineering planning and geotechnical risk mitigation requires the consideration of possible interactions among the hazards and among the vulnerabilities to these hazards. The traditional single-risk approach severely underestimated the total risk and led to engineering failures in the case study. However, quantitative multirisk analysis for landslides is not included in this paper.
