Abstract
The paper analyses the stress state around two elliptical holes that form a head water channel.The stress state is analized in the reinforced concrete consolidation layer around the elliptical holes(the gallerys)as well as in the adjacent rock to the gallerys.The methods used in this analysis are the Finite Element Method and the Boundary Element Method. A statical and a dynamical analysis of the holes is done by means of the two methods.The analysis in the elasto-plastic domain of the material is done by means of the Finite Element Method.The elastic and the mechanical characteristics of the material will be taken into account as well as Von Mises criterion for the elasto-plastic domain.there will be done a comparative analysis in the conditions when for the reinforced concrete layer we admit Von Mises criterion and for rock Drucker-Prager criterion.In the pa per will be presented the diagrams with stress concentrations near the holes too.
