Influência dos constituintes do esgoto no colapso de um solo arenoso

this article evaluates the collapsible behavior of a tropical sandy soil when exposed to different sewage constituent fluids as wetting fluids. the analysis considers the physical, chemical and structural properties of the soil, as well as soil collapsible behavior, the properties of wetting fluids distilled water, domestic sewage, and some solutions composed by substances that constitute sewage, measuring soil deformation in axial compression edometric tests. the physical and chemical properties of fluids and of the soil, as well as their combination, play a relevant role in the comprehension of collapse phenomena, which shows that its occurrence can not be attributed to isolated parameters of soil or fluid.
