... the axial resistances in the contact zone between building structure and rock increase when they approach the isotropic stress state, so that the fluid pressures acting in one-side axial direction can be taken up in the long term without additional technical measures. 2.3 Anhydrite With the salt dome s...

... stress increasing procedure. The deformability of the contact zone is described by the shear stiffness and dilation angle. The analysis of shearing results shows that the concrete to limestone contact behaves in accordance with the constant peak displacement model. 1 INTRODUCTION The contact between...

... conditions, become more hard the requirements to substantiation of strength characteristics for rock foundations and for the contact zone of the rock foundation with the concrete structure. Such a state of things is unavoidable, as with the increase of stresses transmitted from the structure...

In these zones the erosion activity of the river and the formation of recent landslides were concentrated. Rêsume Dans le canyon du fleuve Hrazdan à Erevan les...
