Compacted clayey tropical soils have great potential to be used as barriers in waste disposal facilities, considering that some technical requirements are fulfilled (e.g. hydraulic conductivity; compatibility after disposal; shear strength; swelling/cracking, etc). In turn, the bentonite addition is relevant for the cases where the ...
View ArticleBecause of progressively dumping of plastic wastes (PWs) obtained from beverage industry it is of interest to use them as reinforcement material in civil engineering projects. For assessing potential use of plastic wastes in improvement of shear strength of fine-grained soils, two clayey soils were mixed with different amount of plastic wastes (
The supporting mechanism for overburden strata supported by artificial pillars is a complex issue. A calculation method for the size optimization of an artificial pillar in a deep area based on Protodyakonov’s ground pressure theory was proposed. In this study, the sizes of artificial pillars in different mining sections in a specific mine wer...
View ArticleThe purpose of this paper is to investigate the horizontal stress evolution and soil collapse during the cement dissolution process using a combination of experimental and numerical methods. The experimental procedure was carried out using a modified oedometer cell with horizontal stress measurements and synthetic samples in order to simulate simultaneo...
