This paper presents a comparative analysis using Finite Element Method (F.E.M.) of the foundations with different shapes (cylindrical, truncated cone and hemispherical plate), placed on cohesionless soils with different compaction degrees. The comparison was performed function of the bearing capacity and of the states of stress and deformation that appear in the foundation ground for different load steps to which the foundations are subjected. The foundation systems studied in this paper consist in foundations rea...

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...
