26. Comportamento de estacas tipo escavada e helice continua, submetidas a esforços horizontais / Behavior of bored and continuous flight auger piles under horizontal stress
Nesta pesquisa estudou-se o comportamento de estacas tipo escavada e hélice contínua, submetidas a prova de carga estática horizontal. Estes elementos encontram-se instalados no Campo Experimental da Feagri, Unicamp, cujo perfil compõe-se de solo estratificado predominantemente argiloso, porém com comportamento de arenoso. Como objetivo principal, obtiv

27. Study on factors which affect the accuracy of the filter-paper method. / Estudo sobre fatores que influenciam a acurácia do método do papel-filtro.
The purpose of this work is to verify the susceptibility of the filter-paper method to variations in three experimental parameters: roughness of porous medium (structure of porous matrix), period of exposition of the filter-paper to pore water (equilibration time) and degree of deficiency in contact between the filter-paper and the porous medium. In order to

28. Aspectos e impactos ambientais associados ao processo de injeção da blenda ppo/psai através do inventário do ciclo de vida
In view of that some environmental problems are associated to the industrial production, it becomes necessary to work and to apply concepts for the sustainability. Spite of complex system its possible to accomplish an analysis for the sustainable development through method that support to obtain data and interpretation of the results. Life Cycle Assessment c

29. 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

30. Desenvolvimento de equipamento para ensaios CRS com sucção controlada e ensaios em solos não saturados cimentados artificialmente / Development of equipment for CRS tests with controlled suction and tests with artificially cemented unsatured soils
This research presents the development of equipment for CRS tests with controlled suction and tests with artificially cemented unsatured soils. It was designed and constructed four apparatus at the geotechnical laboratory of the Federal University of Viçosa. The cells have an interchangeable high air entry value ceramic disc on its base. It was also designe

31. 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

32. Use of an equipment cyclic triaxial for study of the liquefaction of fine grained tailings a mixture / Utilização de um equipamento triaxial cíclico para estudo da liquefação de uma mistura de rejeitos de minério de granulometria fina
Este trabalho tem por objetivo analisar o comportamento de um material silto-arenoso quando submetido a carregamentos dinâmicos. Durante o ensaio triaxial cíclico são aplicados ciclos de tensões cisalhantes em uma amostra que elevam os níveis da poro pressão e induz o solo a se liquefazer. Os estudos para determinar o potencial de liquefação de uma m

33. Estudo do comportamento carga VS recalque de estacas raiz carregadas a compressão / Study of the load VS settlement behavior of root piles submitted to compression efforts
In this research, the behavior of the curve load versus settlement ofloaded isolated pile to the compression is analyzed, through forecast methods. Two root piles had been assayed, one with 23m oflength and 31 cm of diameter, and the other with length of 12 m and 41 cm of diameter, in order to attribute the behavior of the interaction ground-pile to one or a

34. 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

35. Banco de dados de curvas de retenção de água de solos brasileiros / Database of soil-water retention curve of brazilian soils
Unsaturated soil mechanics has become an important subject of research devoted to understand the behavior of unsaturated soils and optimize their use in several civil works. The soil-water characteristic curve, defined as the relationship between the suction and the amount of water present in the soil, is considered as the key in the interpretation of the be

36. Evaluation of in-situ bearing capacity of soils in road buildngs through the Dynamic Cone Penetrometer : experimental study / Avaliação da capacidade de suporte de solos "in situ" em obras viarias atraves do Cone de Penetração Dinamica : estudo experimental
This research establishes a correlation among the strength or supporting values of the tests: CBR (California Bearing Ratio) versus DCP (Dynamic Cone Penetrometer), accomplished with the soil originating from no-paved roads inside of the Campus of UNICAMP. The Cone of Dynamic Penetration (DCP) it is characterized as an equipment simple, portable and of low c
