A study of the geotechnical characteristics of collapsible soils from the irrigation channels of Formoso "A" project, Bom Jesus da Lapa country, State of Bahia, is presented. A bibliographic survey on collapsible soils and their characterisation is made at first. Then, physical aspects of the region - geology, pedological types of soils, climate, etc. - are described. This kind of information helps to understand structural features and mechanical properties of collapsible soils under study. Laboratory testing was performed at CEPED, Bahia, and at COPPE/UFRJ. A critical analysis of testing results is presented. Engineering solutions for the channel construction with regard to these soils and climate are shown. Conclusions refer both to the construction features and to collapsible soils characteristics.
