The use of micropiles has been increasing in recent years, mostly for horizontally loaded cases. Given the little information about this foundation type under lateral top-loading, especially in high-porosity and collapsible soils, a total of four tra

In geotechnical engineering, the use of caisson foundations transversally loaded at the top is common. This type of foundation is frequently used on high-porosity and collapsible soils, which are common in many regions in Brazil. Because of the limit

The major problem on geotechnical work is to ensure that no settlements occur during the life cycle of the construction. This involves proper design of foundations and their bearing capacity. The Brazilian standard for design and execution of foundat

Considerando-se que a maior parte de construções rurais utiliza fundações por estacas escavadas, pequisou-se, neste trabalho, o comportamento à tração de três estacas , submetidas a esforços verticais de tração. O comportamento à tração

A região Sudeste do Brasil tem ultimamente apresentado um grande número de processos acelerados de erosões, conhecidos como “voçorocas”. O fluxo superfi cial, de acordo com a forma de escoamento, produz formas de erosão diferenciadas, a sabe
