{"title":"Rainfall-induced landslides: Development of a simple screening tool based on rainfall data and unsaturated soil mechanics principles","authors":"M. Suradi, A. Fourie, C. Beckett, O. Buzzi","doi":"10.1201/b17034-213","DOIUrl":"https://doi.org/10.1201/b17034-213","url":null,"abstract":"There is now widespread acceptance that a key trigger mechanism for shallow landslides is the reduction in soil suction that occurs as a wetting front moves through an initially unsaturated soil profile. Slopes often remain stable at angles steeper than would be predicted using effective stress strength parameters. Such slopes may remain stable for many years, if not decades, with failure only being triggered when moisture conditions within the slope reach a critical threshold. Our understanding of the role of unsaturated soil mechanics in slope stability is now well developed. This paper uses this knowledge to suggest techniques that may be used to provide suitable management tools, the intention being to predict the level of risk associated with a particular slope. The technique combines statistical rainfall data, complemented by confirmation studies using numerical modelling (utilising commercially available software SVFlux and SVSlope), to provide a screening tool that takes account of antecedent conditions; a critical aspect for providing appropriate risk evaluation capability. An approximate approach,which utilizes analytical solutions, is also described. To implement the risk management strategy discussed in the paper, some form of in situ monitoring is required and two alternatives are briefly described: discrete monitoring using buried instruments; and remote sensing of soil water status.","PeriodicalId":294644,"journal":{"name":"Unsaturated Soils: Research & Applications","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125501313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prediction of the fracture structure and flow properties evolution within this zone are major issues especially in the context of underground nuclear waste storage. Since experimental results indicate that shear strain localisation appears prior to fractures, we model the EDZ with strain localisation in shear band mode using the coupled local second gradient model. The evolution of the intrinsic hydraulic permeability inside the fractures is taken into consideration as well as the influence of gallery ventilation on the rock desaturation. The numerical results provide information about the damaged zone extension, structure and behaviour with good correspondence to in situ measurements and observations.","PeriodicalId":294644,"journal":{"name":"Unsaturated Soils: Research & Applications","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134276230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
