Laboratory tests were conducted in soft clay deposits at the Macae/RJ airport in order to obtain geotechnical parameters for a new runway design. The quality of soil samples, extracted with both brass tube (thin-walled) and reinforced PVC tube (thick-walled) soil samplers, was assessed. Both samplers were 700 mm long, with a 7 degree chamfered cutting edge and n...

This paper applies Bayesian updating of the load capacity of a large steel piling foundation for the high load structure of the Alcântara Wastewater Treatment Plant (WWTP), located near the city of Rio de Janeiro in Brazil. Uncertainty is modeled by a priori and a posteriori distributions of the piling capacity. The a posteriori distribution is determined ...

This article compares and analyses the behaviour of three test embankments. The soil foundation consisted of normally consolidated clay overlain by a thick sand surface layer. The embankments were rapidly constructed until failure, which occurred after approximately 50 days. Two of the embankments were reinforced, one including prefabricated vertical drains (...
