The wind energy is a modern and efficient solution that uses the air flow through wind turbines to mechanically power generators for electric power production, being an alternative to burning fossil fuels. Wind power is renewable, widely distributed, produces no greenhouse gas emissions, consumes no water and uses small land areas. A wind turbine converts the kinetic energy of the wind into electrical energy. The electrical power generator and the steel upper structure of a wind turbine are equipments where were i...

The object of this paper is represented by the analysis of a grid foundation for a light reinforced concrete structure. The need for this kind of analysis was imposed by the foundation ground conditions. In the case of sites presenting differentiate foundation ground conditions in the perimeter of a construction it is necessary a detailed analysis of the foundation conditions of the site and also, the behavior of the ensemble of the entire structure. So, is stent an adjustment of the foundation solution to the sit...

The paper starts with the presentation of some general elements for characterizing, from morphological, geological, climatic, rainfalls and hydrographical point of view, a national road routing, highlighting the specific particularities which are concerning the study of the instability phenomena. Further on, are presented the types of instability phenomena present on the national road routing, including the general causes that produced them. The paper ends with the analysis of two case studies, considered as being...
