The objective of this study is to create a geological-geotechnical risk map of mass movement for an urban perimeter of Rio Piracicaba city, state of Minas Gerais, MG, Brazil, by applying the methodology proposed by the Brazilian Ministry of Cities. Four neighborhoods were evaluated through works conducted in the field and with the aid of a GIS fed with aerial im...

Ultrasonic longitudinal wave velocity (Vp) and durability are characteristics largely determined in geotechnical evaluations. These properties are useful in the analysis of weathered rocks because they usually have good relationships with physical and mechanical properties of rocks. Additionally, the tests to obtain these parameters are easy to perform. However,...

Soil nailing has proved to be an efficient and cost-effective stabilization technique, consisting in installing passive reinforcement in the soil that provides the material with tensile and shear strengths. The fundamental parameter in analyzing the mechanical behavior of this type of structure is the frictional resistance of the soil-nail interface, denominated...
