A new kind of reinforced Deep Cement Mixing (DCM) pile, namely: Stiffened Deep Cement Mixing (SDCM) pile is introduced to mitigate the problems due to the low flexural resistance, lack of quality control in the field and unexpected failure of DCM pile. The SDCM pile consists of DCM pile reinforced with precast concrete core pile. Previously, the full sc...
View ArticleThe use of prefabricated vertical drains with vacuum preloading and surcharge preloading is now common practice and is proving to be one of the most effective ground improvement techniques known. The factors affecting its performance, such as the smear zone, the drain influence zone, and drain unsaturation, are discussed in this paper. In order to evalu...
View ArticleThis work studied the transport phenomena in the soil of the Gramacho MSW landfill located in Rio de Janeiro,
Brazil. A model was proposed to determine the mass transfer rate of the leachate contaminant ions to the soil particles.
Previous researchers have focused on the diffusion and sorption phenomena using simple relations tha...
After a short period of relatively intense rainfall, a deep-seated landslide occurred in a slope in Rio de Janeiro.
On the following day, field inspection revealed full saturation of the failure mass, despite the inexistence of groundwater in
the slope. A comprehensive experimental investigation was undertaken to determine the ge...
