1. Waste disposal using a spreader and conveyor belt method
Abstract In the search for opportunities to decrease operational costs in iron ore mining, waste disposal by conveyor belt has been considered as an alternative. In this work, this form of waste dump is investigated by means of the construction of a test pile and the assessment of geotechnical characteristics such as shear strength and in situ densities. Res

2. Integrated study of geological and geotechnical characteristics for aquifer recharge assessment: São Carlos-SP region / Estudo integrado das características geológico-geotécnicas com vista à avaliação de recarga de aquífero: região de São Carlos-SP
This thesis presents an integrated study of the geological and geotechnical characteristics of São Carlos region which influence the recharge process of the aquifer composed of sandstones of the Botucatu Formation. Among the assessed characteristics, it can be distinguished the parameters of ydraulic conductivity, retention of pollutants and pore distributi

3. Zoneamento geotécnico com base em krigagem ordinária e equações multiquádricas: barragem de Itaipu / Geotechnical zoning based in ordinary kriging and multiquadric equations: Itaipu Hydroelectric Power Plant
This thesis presents a study based on the zoning of geotechnical parameters resulting from core boring, carried out in the basaltic bedrock located in the area of the Itaipu Hydroelectric Power Plant (Foz do Iguaçu - PR). These zonings were carried out based on the interpolation of the data by means of ordinary kriging and multiquadric equations. The data p

4. Uso das técnicas HCT e TDR no monitoramento do proceso de consolidação em reservatórios de barragens de rejeitos / Monitoring of consolidation process in deposits of tailings dam by TDR and HCT techniques
The mining industry generates a large amount of tailing, which is usually placed in tailing dams. To properly design these constructions, when the tailing is highly compressible, it is necessary to study the consolidation characteristics of this material by means of techniques that consider large deformations. This study aimed to establish the technique HCT

5. Retroanálise probabilista aplicada à análise dinâmica da cravação de estacas. / Probabilistic back-analysis applied to dynamic loading test for pile driving.
An dynamic loading test can be performed in concrete piles, bored piles, drilled shafts, auger cast-in-place (continuous flight auger) piles. Such essay bases on the Theory of the Propagation of Wave in piles with the aim of evaluate the capacity of static load mobilized from the dynamic event. The analysis of the test is made by a PC program (p.e. CAPWAP or

6. Uso do DMT na avaliação de maciços compactados
The quality of compacted fill, be they of road works or dams, is essential to the smooth functioning of work as a whole. Currently, the quality control of this is done by testing that determine the diversion of moistures soil newly compacted, in relation to optimum moisture content, and the degree of compaction achieved. Based on these results characteristic

7. AvaliaÃÃo da retenÃÃo de gases em camadas de cobertura de aterros de resÃduos sÃlidos
Municipal solid waste landfills final covers work as a seal interface between the wastese and the external environment. This sealing layer is also responsible to avoid the infiltration of water into the waste mass and the emission of gases to the atmosphere. These interventions show by they own how important are both project and execution of the top cover as

8. CaracterizaÃÃo geotÃcnica de um solo de calcÃrio da Encosta Continental/PE-18, Paulista-PE, com Ãnfase na resistÃncia ao cisalhamento
The main objective of this dissertation is the study of the geotechnical characteristics, of the layer of calcareous silty clay involved in the landslides that occurred in an area situated in highway BR 101 North, PE 18, in the industrial district of Paulista, with emphasis in its shear strength. A slope with instability problems between highway PE- 18 and t

9. ESTUDO DO ADENSAMENTO E RESSECAMENTO DE RESÍDUOS DE MINERAÇÃO E PROCESSAMENTO DE BAUXITA / RESEARCH ON CONSOLIDATION AND DESICCATION OF BAUXITE MINING AND INDUSTRIAL PROCESSING WASTES
This work presents the methodology used to study the consolidation and desiccation of bauxite wastes from mining and industrial processing. The aim is to understand the geotechnical behavior of these wastes launched as slurries in reservoirs and then, let do dry under solar exposure. Five types of residues are here considered. The first is an inert waste res
