The response of a massif to stresses generated by tunnel excavation depends essentially on the geological conditions, geometry and its underground position. major problem related construction these structures is ensure stability whole tunnel-ground, controlling various deformation during construction. In this context, present paper examines effect conditions behavior tunnels surrounding soil. s...

Este artigo tem o objetivo de avaliar comportamento da fundação um aerogerador situado no nordeste do Brasil. O projeto original torre não considerou contato radier-solo desempenho sistema. Dessa forma, presente trabalho propõe considerar radier-solo, ou seja, assumir que a é radier estaqueado e impacto dessa premissa fundação. As análises foram realizadas por meio dois softwares elementos fini...

tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. the predication of ground movement during the tunnelling and optimum support pressure could be based on analytical, empirical or the numerical methods. the commonly used earth pressure balance (epb) tunneling machines, uses the excavated soil in a pressu...

The use of wind turbines to generate electricity has increased in recent years. One of the most important parts of a wind turbine is the foundation, which should be designed accurately because it is influenced by difference forces. Soil cannot carry tension stress; thus, when a wind turbine foundation is applied eccentricity forces, a gap appears between the soil and foundation. The gap will ha...

A comparison of the calculation results foundation pit enclosure made flexible retaining walls is presented. Calculations were performed by method numerical modeling using Plaxis PC software, which based on finite element method. This task was implemented in three-dimensional (3D) and flat (2D) formulations problem, provides more opportunities for a comprehensive assessment stress-strain state ...
