This paper presents a new method for predicting the axial capacity of piles from dynamic penetration tests which is based on the concepts of soil dynamics and principles of energy conservation. The energy delivered to the hammerrod-sampler system and transferred to the soil is computed from the numbers of blow counts N_spt and is a...

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...

This paper presents and discusses a limited set of results from an extensive testing program which has been
carried out since 1995 at the University of Brasília Experimental Research site. This site is underlain by the typical tropical,
unsaturated and collapsible soil deposit of the Federal District, which ha...

This work analyses the influence of footing size and soil matric suction on the behavior of shallow foundations on unsaturated sandy soil, in terms of bearing capacity and settlements. Fourteen plate load tests were performed at the Experimental Site of USP/São Carlos. Rigid metal plates were used, with diameters varying between 0.20 m and 0....
