1. SORM DG - an efficient SORM based on differential geometry
Abstract The first order reliability method (FORM) efficiently performs first order structural reliability analysis, but with limited accuracy. On the other hand, the traditional second order reliability method (SORM) was established to improve the results of FORM, but with a supplementary computational process. Proposed herein, is a new SORM, based on diffe

2. Analysis of the contribution of the block-soil contact in piled foundations
Abstract Geotechnical engineering has often been challenged by demands from technically and economically bold construction projects, such as that of tall buildings. The architectural requirements of these buildings have increased and concentrated the loads from structural systems without proportionally increasing plant area. New forms of using load capacity

3. Redes neurais com topologias otimizadas aplicadas na modelagem de dados geotécnicos e pluviométricos para predição de deslizamentos de solo
The problems related to landslides caused by rain on slopes have been a reality in several cities of Brazil and parts of the world. The government and research institutions have sought, in partnership, solutions to minimize the damage caused by such accidents, from studies of correlation between rainfall and landslide occurrences enabling the development of

4. Banco de dados geológico-geotécnicos com base em sondagens à percussão e uso de SIG: análise espacial da profundidade do lençol freático e do \ N IND.SPT\ para obras de fundação em João Pessoa - PB / Geological-geotechnical Database with SPT sounding data and GIS: spatial analysis of water table level and \ N IND.SPT\ values applied to foundation maps in João Pessoa - PB (Brazil)
Geological-geotechnical databases have been used as important assistant tools in urban and environmental management activities. However, the kind of information necessary for one to work with such tools may not always be available or easily supplied. This work concerns the generation of a Decision Support System undertaken through means of a Geographic Infor

5. Análise numérica 3D do túnel auxiliar a jusante da UHE simplício-anta / 3D Numerical analysis of the tunnel downstream of the auxiliary
With the accelerated occupation of the space, the use of tunnels play an important role in engineering, in this sense, the deformations control during it s construction process is very important for the best performance of tunnels. In this sense the numerical analyzes represent a likely economy in the design process. This paper uses a theory of elasticity in

6. Influência de variáveis de compactação na estrutura dos solos: caracterizações geotécnica, química, mineralógica e microestrutural / Influence of laboratory compaction variables in soils structure: geotechnical, chemical, mineralogical and microstructural characterizations
This research addressed the effect of laboratory methods of static and dynamic compaction on compaction parameters, mechanical strength and compressibility of three gneiss residual soils (two young and one mature soils) and two granite residual soils (one young and one mature soils) from the Minas Gerais State, Brazil. Disturbed soils samples were collected,

7. GEOWEB, um facilitador para a aprendizagem em geotecnia / GEOWEB, a facilitator for learning in geotechnical
Historically and with more emphasis on the international level, efforts have been dedicated in the design and implementation of Learning Objects for the teaching of soil mechanics courses in Civil Engineering, in particular, to the topic of Water Movement in Soil. Following this vision, this paper examines the relationship between teaching and learning in th

8. Jet Grouting (sistema monofluido): um método teórico simplificado para a previsão do diâmetro das colunas. / Jet Grouting (single fluid system): a theoretical simplificated method for the prediction of column diameter.
Jet grouting is one of the most popular ground improvement techniques all over the world. The method is based on high-speed grouting of water-cement mixtures and/or other fluids (air, water) into the subsoil. The fluids are injected through small diameter nozzles placed on a grout pipe, which is continuously rotated at a constant rate and slowly raised towar

9. 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

10. DIAGNÓSTICO AMBIENTAL URBANO DO MEIO FÍSICO DE SANTA MARIA RS / URBAN ENVIRONMENTAL DIAGNOSTIC OF SANTA MARIAS PHYSICAL SPACE IN THE STATE OF RIO GRANDE DO SUL
The urban environment diagnosis aims at subsidizing the districts in the decisionmaking in the presence of natural resources preservation. This study, specifically, analyze the urban environment aspect of the physical space. The area of this study is the Map of the Geotechnical Engineering Units according to Maciel Filho (1990) of Santa Maria, located in the

11. Análise do comportamento de estacas strauss submetidas a carregamento horizontal no solo da região de Londrina - PR
In Londrina city, Strauss piles are frequently used as retaining structure for building basement excavation, being submitted to horizontal load. However, the projects of such retaining structures are usually conducted using design methods that do not take the concrete cracking of pile transversal section and the properties of lateritic tropical soil into acc

12. APLICATIONS OF PROBABILITY AND STATISTICS IN GEOTECHNICAL ANALYSES / APLICAÇÕES DE PROBABILIDADE E ESTATÍSTICA EM ANÁLISES GEOTÉCNICAS
In geotechnical analyses, forecasts of safety factors or deformations are developed on the basis of deterministics methods, that admit as fixed and known the parameters of the soil or the rock. However, such forecasts are affected by uncertainties proceeding from the reproduction impossibility of the field conditions in laboratory, of the disturbance of the
