25. CARACTERIZAÇÃO FÍSICO-QUÍMICA-MINERALÓGICA E MICROMORFOLÓGICA DE UM PERFIL DE ALTERAÇÃO DE ROCHA ALCALINA DO RIO DE JANEIRO / RESIDUAL SOIL ALKALINE ORIGIN CHARACTERIZATION AT THE TANGUÁ CITY, RIO DE JANEIRO
The behavior of rock decomposition products has been studied by many authors throughout the country. These works have great importance for the geotechnical engineering, mainly in tropical regions, with hot and rainy climates, like it is found in Brazil, since atmospheric conditions have a great influence in the soil formation originated from the mother rock.

29. STUDY ABOUT THE BEHAVIOR OF SLAB-ON-GRADE CONCRETE FOUNDATION SETTLE ON SEDIMENTARY SOIL IN THE SANTA MARIA REGION / ESTUDO DO COMPORTAMENTO DE SAPATAS DE CONCRETO ARMADO ASSENTES SOBRE SOLO SEDIMENTAR DA REGIÃO DE SANTA MARIA
Superficial foundations transfer the load to soil by the distributed tensions on the base of the foundation element and, projects are normally conditioned to crack and displacement criteria. In the ordinary engineering practice, especially in the Santa Maria region, due to the absence of constitutive models and experimental data, empirical and semi-empirical

31. Caracterização geofísica de alvos rasos com aplicações no planejamento urbano e meio ambiente: estudo sobre o sítio controlado do IAG/USP / Geophysics characterization of shallow targets with applications in the urban planning and environmental: Study on the Shallow Geophysical Test Site of IAG/USP.
The implantation of the Shallow Geophysical Test Site (SCGR) of the Astronomy, Geophysics and Atmospheric Sciences Institute (IAG), from University of Sao Paulo (USP), is a mark in national geophysical history. It is the first site Shallow geophysical study site installed in Brazil. This Test Site is located next to Physics Institute in front of IAG/USP, com

32. Estudo geotecnico de um solo superficial da cidade de Bragança Paulista, SP / Geotechnical study of the superficial soil at Bragança Paulista, SP
The survey has the objective to investigate the geotechnical behavior of a typical soil profile at Bragança Paulista city - São Paulo State - Brazil. This profile is classified by the pedology as Red Yellow Oxisoil. To achieve this aim were accomplished characterization geotechnical tests, triaxial tests and consolidation tests. In the characterization tes

33. Alternativa de melhoramento de solos tropicais para uso em sistemas basais de selagem, através da aplicação de bentonita
Among all the constructive elements in waste containment systems (e.g. sanitary and industrial landfills and waste ponds), liners and cover systems have been seen as the greatest concern. In Brazil, the use of compacted lateritic soil for this purpose is widely accepted, due to the great occurrence of this type of soil. At the same time, the proposal of usin

34. Geological-geotechnical characterization of the uncontrolled sanitary landfill of São Carlos-SP / Caracterização geológico-geotécnica do lixão desativado de São Carlos-SP, com auxílio da geofísica
Unfortunately the brazilian cities, in its majority, discharge its domestic solid wastes without any control, which produces grave consequences such as contamination of the air, earth, and both superficial and the groundwater. This work carried out a geological-geotechnical characterization and geophysical studies of the uncontrolled sanitary landfill of Sã

36. Estudo geolÃgico â geotÃcnico do processo erosivo em encostas no parque metropolitano armando de holanda cavalcanti - Cabo de Santo Agostinho/PE
Water erosion for if dealing with to a so vast and complex subject and as many implications need to be monitored, to be analyzed and to be understood in some scales. The inquiry campaigns must be based mainly on the involved mechanisms in the process. It is necessary to have relative information of the way, in what it says respect to the possibility of diffe
