14. 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.

17. STUDY ABOUT THE BEHAVIOR OF SLAB-ON-GRADE CONCRETE FOUNDATION SETTLE ON SEDIMENTARY SOIL IN THE SANTA MARIA REGION / ESTUDO DO COMPORTAMENTO DE SAPATAS DE CONCRETO ARMADO ASSENTES SOBRE SOLO SEDIMENTAR DA REGIÃO DE SANTA MARIA
Superficial foundations transfer the load to soil by the distributed tensions on the base of the foundation element and, projects are normally conditioned to crack and displacement criteria. In the ordinary engineering practice, especially in the Santa Maria region, due to the absence of constitutive models and experimental data, empirical and semi-empirical

19. BACK ANALYSIS OF FORMATION OF SOFT MINING TAILINGS DEPOSITS / RETROANÁLISE DA FORMAÇÃO DE UM DEPÓSITO DE REJEITOS FINOS DE MINERAÇÃO CONSTRUÍDO PELO MÉTODO SUBAÉREO
The growing mineral exploration generates increasing amounts of mining tailings that need to be properly disposed, requiring larger and larger areas. The conventional way of tailings disposal consists of spigotting tailings in a pulp form within an impoundment. This practice generates low density, compressible and soft deposits. These characteristics, which

20. 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

21. ESTABILIDADE E DEFORMAÇÃO DE TALUDES DE SOLO SOB CARREGAMENTO SÍSMICO / STABILITY AND DEFORMATION OF SOIL SLOPES UNDER SEISMIC LOAD
The seismic stability of slopes has been a topic of considerable interest in geotechnical engineering for the past 40 years. During that period, the state of practice has moved from simples techniques to more complicated numerical procedures. The simplest approach is the pseudo-static analysis in which the earthquake load is simulated by an equivalent static

22. Estudo do comportamento de túneis: análise numérica tridimensional com modelos elasto-plásticos. / Study of the behaviour of tunnels: elasto-plastic constitutive model three-dimensional numerical analyses.
The present research approaches the study of the behaviour of tunnels in soil. It is given emphasis in the application of numerical analyses using different elasto-plastic constitutive models for soils. Three-dimensional numerical analyses of a widely instrumented tunnel belonging to the Company of the Metropolitan of São Paulo are presented. The analyses a

23. ANALYSIS OF GEOGRID REINFORCED SOIL TESTS / ANÁLISE NUMÉRICA DE ENSAIOS EM SOLO REFORÇADO COM GEOGRELHA
The use of geosynthetic materials as reinforcement in geotechnical engineering works is significantly increasing over the past decades. Geogrid, whose primary functions is reinforcing the soil mass, is one of the geosynthetics that has been used. In a reinforced soil structure, there are different types of interaction between soil and geogrid. To be possible
