25. REINFORCEMENT OF LATERITIC SOIL WITH RANDOMLY SISAL FIBERS DISTRIBUTED TREATED WITH RECYCLED EPS / Reforço de Solo Laterítico com Fibras de Sisal de Distribuição Aleatória, Tratadas Superficialmente com EPS Reciclado
The high costs of the civil engineering construction requires the necessity to develop studies about the process of the stabilization and reinforcement which improves some geotechnical soils properties being part of the constructive specifications. The reinforcement technique of the soils with the inclusion of natural fibers has been studied for many researc

26. Sobre a modelagem de problemas da engenharia geotécnica pelo método dos elementos finitos. / about geotechnical engineering mModelling using finite element method.
Tradicionalmente, a análise de problemas da Engenharia Geotécnica esteve apoiada nos conceitos da Mecânica dos Solos, desenvolvida por Terzaghi, na Teoria da Elasticidade e nas teorias de análise limite. Este trabalho busca explorar uma abordagem que deveria ser mais utilizada neste tipo de problema, voltada à utilização de modelos constitutivos mais

28. WEATHER-RELATED GEO-HAZARD ASSESSMENT MODEL FOR RAILWAY EMBANKMENT STABILITY
The primary objective of this thesis is to develop a model for quantification of weather-related railway embankments hazards. The model for quantification of embankment hazards constitutes an essential component of a decision support system that is required for the management of railway embankment hazards. A model for the deterministic and probabilistic asse

29. GEOTECHNICAL CHARACTERIZATION OF A SOFT CLAY DEPOSIT IN BAIXADA FLUMINENSE / CARACTERIZAÇÃO GEOTÉCNICA DE UM DEPÓSITO DE ARGILA MOLE DA BAIXADA FLUMINENSE
This work has focused on the geotechnical characterization of a soft clay deposit in Baixada Fluminense, Rio de Janeiro. In this area, a large embankment of approximately 500.000m2 was executed for implantation of Rio Polimeros Industry. An extensive laboratory program was carried out on undisturbed samples, extracted from the soft clay layer before embankme

30. COMPORTAMENTO GEOTÉCNICO DA BARRAGEM DE CURUÁ-UNA, PARÁ / GEOTECHNICAL BEHAVIOR OF CURUÁ-UNA DAM, PARÁ.
The geotechnical behavior of Curuá-Una dam, Pará, was studied due its importance to the North Region of Brazil. The power plant, in operation since 1977, is located in the Amazon forest, next to the city of Santarém. The study was comprised of the evaluation of current operation conditions of the dam and prediction of its performance after a possible rise

31. ESTUDOS DA DEFORMABILIDADE DE ESCAVAÇÕES COM SOLO GRAMPEADO / DEFORMABILITY ANALYSIS OF SOIL NAILING EXCAVATIONS
The use of passive inclusion for soil reinforcements, technique usually known as soil nailing, has been gaining growing acceptance within civil engineering professionals, especially in Rio de Janeiro. However this technique lacks a more detailed study on the elevant parameters influencing the deformability of soil nailed masses. The nails are rigid inclusion

33. ANÁLISIS DE PROBLEMAS GEOTÉCNICOS A TRAVÉS DE REDES NEURALES / ANALYSIS OF GEOTECHNICAL PROBLEMS WITH NEURAL NETWORKS / ANÁLISE DE PROBLEMAS GEOTÉCNICOS ATRAVÉS DE REDES NEURAIS
During the last years, neural networks applications have been disseminated in many knowledge areas, including civil engineering. In the middle 90`s, a research work had been started in Brazil, in order to investigate the efficiency of neural networks in the analysis of soil behavior and problems involving geotechnical engineering. This thesis is the result o

34. IMPLEMENTACIÓN NUMÉRICA PARA EL ESTUDIO DE FUNDACIONES FLEXIBLES EN SUELOS ESTRATIFICADOS / NUMERICAL ANALYSIS OF FLEXIBLE FOOTINGS ON STRATIFIED SOILS / IMPLEMENTAÇÃO NUMÉRICA PARA ESTUDO DE FUNDAÇÕES FLEXÍVEIS EM SOLOS ESTRATIFICADOS
Many problems of geotechnical engineering can be solved by superposition of the fundamental singular solutions to the governing differential equations. In the dissertation, the mechanical behavior of a flexible footing is investigated, in terms of stress and settlement distributions, considered some basic fundamental solutions published in literature. These

35. APLICAÇÃO DO MÉTODO DOS ELEMENTOS FINITOS NA ANÁLISE DA ESTABILIDADE DE TALUDES EM SOLO / APPLICATION OF THE FINITE ELEMENT METHOD FOR SOIL SLOPE STABILITY ANALYSES / APLICACIÓN DEL MÉTODO DE ELEMENTOS FINITOS EN EL ANÁLISIS DE ESTABILIDAD DE TALUDES EN EL SUELO
The main objective of this research is the application of the finite element method (FEM) to analyze the stability of soil slopes, searching the position of the failure slip surface in the soil mass and its corresponding safety factor. The finite element method has become a popular tool for the study of many geotechnical engineering problems but, in the spec
