Abstract

The identification of elastic constants of stratified rock through large-scale in-situ tests with an hydraulic pressure chamber is discussed. Above all the anisotropy parameters of a stratified mass have been stated as a function of moduli and thicknesses of the layers. The influence of the stratification is analysed with reference to the equivalent crystalline anisotropy. Experimental measures performed by a special technique in a stratified rock mass consisting of alternating layers of sandstone and marl have been analysed and interpreted in comparison with the results of the theoretical approach. Finally the most recent development of ismes testing technique is illustrated and discussed. The number of the covering abstract of the congress is TRIS no. 385148. (TRRL)
