2. EVALUATION OF STABILITY CONDITIONS OF THE JARDIM GRAMACHO LANDFILL / AVALIAÇÃO DE CONDIÇÕES DE ESTABILIDADE DO ATERRO METROPOLITANO DE JARDIM GRAMACHO
O Aterro Metropolitano de Jardim Gramacho (AMG) é o local que recebe desde 1976 os resíduos sólidos gerados pelas atividades domésticas, além das comerciais e industriais da área metropolitana do Rio de Janeiro. Atualmente no AMG vem se desenvolvendo projetos de aterramento até o ano 2012, portanto, a estabilidade dos taludes do maciço cresce em impo

3. Desenvolvimento de equipamento para realização de ensaios HCT com o uso da bomba de fluxo
In general, the tailings are disposed in the form of pulp, mainly because the condition of the residue is the natural byproduct of the minerals concentrations activities, always associated with large water demands. The final disposal of wastes in pulp occurs by hydraulic filling techniques in large reservoirs of check dams. In the case of more granular taili

4. Estudo da correlação entre resistência mecânica e velocidade ultrassônica para um material terroso
This dissertation presents the studies carried out on the applicability of ultrasound as a non-destructive evaluation method of the structural conditions of earth structures designed to building rammed earth. To this purpose the ultrasound was defined as a proposal for utilization of a non-destructive method on the evaluation of the relation of earthy materi

5. Analysis of mechanical behavior of an expansive soil from the oil province of Urucu-AM for paving / Análise do comportamento mecânico de um solo expansivo da província petrolífera de Urucu-AM para fins de pavimentação
The establishment of transportation infrastructure is critical to the development of the Urucu- AM region, a newly developed oil exploration area in the Amazonas state. The construction of such infrastructure is challenging due to the lack of suitable materials for the construction pavement base and subbase courses and adverse weather conditions, with altern

8. GCL shear strength evaluation - a new test method / Avaliação da resistência ao cisalhamento em GCLs - uma nova metodologia de ensaio
GCLs (Geosynthetic Clay Liners) are geosynthetic products used to compose flux control barriers in geotechnical and environmental works. The mechanical properties of GCLs have to be investigated in short and long term. Among its mechanical parameters, GCL internal shear strength plays an important role in the stability of slopes of geotechnical works. The ma

9. Evaluation of field performance of cover systems at Rio Paracatu Mine (RPM) / Avaliação de desempenho de sistemas de cobertura na mina Rio Paracatu Mineração (RPM)
In view of the RPM need to study soil covering systems and the scientific interest in those studies, two experimental evapotranspirative cover systems were projected and built, one with and, the other, without, a layer of capillary barrier, both with a monitoring system composed by superficial drainage meter, lisimeters to measure infiltration and geotechnic

10. Avaliação de uma sonda TDR helicoidal para a estimativa do teor de umidade de solos em campo e laboratório / Evaluation of a helicoidal TDR probe to estimate the soil water content in laboratory and in situ
In this work is presented the evaluation of a recently developed helicoidal probe used for estimating the soil water content through the time domain technology (TDR). This probe has been calibrated in laboratory for different types of soils. The calibration process consisted in assessing the values of the apparent dielectric constant (Ka) and the bulk electr

12. 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.
