Preloading with vertical drains is a well-proven ground improvement technique suitable for soft clay deposits. This technique involves installing vertical drains that cause soil remolding in the immediate vicinity of its surface, creating a disturbed zone known as the smear zone. This study aims to investigate the impact of overburden stress on the char...
View ArticleDuring operation, the ballast is subjected to a gradual breakage process that causes clogging of the substructure. Intervention periods on the ballast layer generate high costs that impact the long-term competitiveness of railways. In this context, this work aims to evaluate the geomechanical behavior of reinforced ballast, assessing the effect of reinf...
View ArticleHelical piles are steel elements consisting of one or more helices placed along a central shaft and installed in the ground through rotation. This study describes a field investigation of the behavior of a helical pile prototype subjected to cyclic tensile loads in a site composed of pure sand layers. During the investigation, the helical pile prototype...
View ArticleThe demand for tunnels in densely populated urban areas is growing rapidly to address mobility challenges. Mechanized tunneling is widely adopted in urban environments due to its high productivity and the relatively small ground deformations it induces. However, urban tunneling is highly complex because of the typically shallow depths and interactions w...
