In other words, civil engineering is only possible where there is soil. Construction professionals should not face any obstacles when building sustainably in any soil context. Knowledge of the altimetric state, including hills, mountains, valleys, etc., and the subterranean state, including obstacles such as compressible soil, holes, water tables, and rock masses, is crucial to consider before designing infrastructure. This includes the buried part of a structure and the angle of the natural slope in the superstructure to avoid landslides in the infrastructure. Landslides are natural disasters that have had a devastating impact on several populated areas in Cameroon, resulting in numerous fatalities. The most recent landslides recorded in our country occurred in NGOUACHE, MBANKOLO, MOBIL GUINNESS, among others. Preventing disasters requires an understanding of the relationship between construction and landslides to minimize their occurrence and impact. It is important to campaign for sustainable construction that respects the environment. Understanding landslides involves both destructive and non-destructive approaches. This article presents numerical methods for analysing and predicting phenomena. Among these methods, we focus on the discrete element method, which represents the medium as an assembly of circular, rigid particles. We examine three cases to observe the behaviour of the supporting soils and determine the fracture surface. Additionally, we compare our results with those found in the literature.\u0000","PeriodicalId":262934,"journal":{"name":"Journal of Civil, Construction and Environmental Engineering","volume":"107 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141812165","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}

In order to manage them safely, the present work aims to evaluate their potential to be reused in the construction industry, hence, it is intended to use the drilling cuttings contaminated with diesel as a partial replacement for the conventional raw material for the Manufacture of asphalt pavement. To determine the composition of the dry and wet drill cuttings, physical, chemical and mechanical tests were carried out that showed a hydrocarbon content of 3.2% and 6.9% respectively, higher than the maximum limit established for final disposal, due to the presence of diesel in the composition. Regarding its granulometry, it is evident that more than 70% of its particles are fine, so it can be used as a modifier of the granulometry of the aggregate. Different mixing ratios were established to improve their properties in the application proposal, obtaining viable results. In this regard, resistances of 46%, 33% and 32% higher than the minimum limit were obtained to be used in pavement patching actions as a subbase. Elements that drill cuttings can replace conventional raw materials such as aggregates or aggregates in the restoration of sub-base of asphalt pavements, this management alternative being beneficial from an environmental point of view.","PeriodicalId":262934,"journal":{"name":"Journal of Civil, Construction and Environmental Engineering","volume":"480 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140750762","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}

Most parts of the area have experienced crude oil contamination of one form or the other, and the effects on man and the ecosystem are wide ranging. This study has examined the effect of oil contamination on the compaction behaviour of two clay samples obtained at shallow foundation depths in Yenagoa. The two clay samples, A and B are classified according to the unified soil classification system (USCS) as high plasticity inorganic sandy fat clay, and sandy lean clay, respectively. 4, 8, and 12 % crude oil by mass of dry soil were used to mix with the soil samples and left to cure in plastic bags for 48 hours before testing. In sample B, liquid limit (LL) was found to increase by about 9% for all proportions of crude oil while plastic limit (PL) was increased by 13%, 15%, and 27% for 4, 8, and 12 % oil content, respectively. These increase in LL and PL also brought about an increase in plasticity index except for 12% crude oil treatment. However, in all, a low plastic soil was changed to a slightly high plastic one as plotted on the Casagrande chart. The maximum dry density (MDD) of the two samples was also reduced by oil contamination with an increasing oil content exacerbating the reduction of MDD. It is therefore, recommended that care be taken during construction when dealing with clay soils within a potential crude oil contaminated region.","PeriodicalId":262934,"journal":{"name":"Journal of Civil, Construction and Environmental Engineering","volume":"257 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140445956","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}
