DETERMINATION OF ROCK MASS MODULUS

In order to assess the behaviour of a rock mass when an engineering function is performed on the rock mass the deformational response must be assessed. To do this the rock mass and the associated defects in the form of joints and faults are classified and a geological model is built up. Quantification of this geological model is required if the behaviour of the rock mass to the imposed engineering function is to be predicted. Both laboratory and field tests are performed. A simple plate bearing jacking field test is described and its cross correlation with a numerical model representing the geological model of the rock mass is described. Results of the laboratory tests are used in the numerical model and the resultant deformational response is compared with the deformational response of the plate bearing jacking field test. Results of the deformational response are not presented as these are given elsewhere in another paper. Nevertheless, correlation of the rock mass rating with deformational modulus and the Poisson's ratio of the rock mass is proposed. (Author/TRRL)
