... mass calculated in three-dimensional space can be plotted in a hemispherical diagram. From this diagram one can find the value of the deformation modulus in any given direction and even an estimate of the average overall modulus. INTRODUCTION The deformability of jointed rock masses is associated...

... pressure diagrams are still used for stability analyses of concrete structures founded on rock, particularly during preliminary studies. Piezometric measurements on several brazilian dam foundations were collected and analyzed. These mea- surements were taken at both rock-concrete contact...

... the effect of the transfer of load on the foundations of dams and other structures. It has been found from field studies of existing dams that the inclination of the rock foundation beds influences substantially the shape of the diagram of the load transferred on the structure. Inclination of beds of rock...

... of the heteroge- neous roof of adjacent chambers is solved by two methods. At first the calculation for initial rock lamination is performed, then the rock scaling possibility is deter- mined. The diagram for the calculation is shown in Fig. 1. y Fig. 1. The,diagram for stress- strain condition determination...
