CORPS ENGIN~S,OMAHA, MRD-4-75, JULY 1975,290P • An investigation of the mechanical influence of interstitial fluids on the deformation process of saturated rocks has been conducted to determine the domain of validity of l~eviously published theories. Equilibrium equations for fluid saturated materials in whlch the fluid is at rest or flows according to Dsrcy's law were derived. For this purpose s a new characterization of porosity has beau proposed for analyzing porosity variations within a rock nmss. In view of the results obtained, three effective stress theories for the analysis of elastic deformation in saturated rocks are discussed. 17o7

SOIL MECH. FOUND. ~GNG, Vll, N5, S~I~T-OCT .1974, P325 -330. It is demonstrated that the swelling deformations caused by collapse are related not only to surface phe~omema in the pore spaces of the soll but also to complex physicochemical processes which occur inside the crystal structure of the mineral particles of these soils.

Numerical s1~11atlon of dlscontinua is achieved through development of the finite element technique. The essential feature of the method is the reco@~ition of the ms4or importance of interblock displacement while intrablock deformations are treated as second order affects. The mechanics of a jointed medium is related to rigid body displacements of adjacent block centroids through rectilinear elements which simulate normal s ~ tangential compliance of the units. Full account is taken of nonlinear interactions between blocks. Normal interaction between blocks allows for limited tensile strength, locking in both compressional and rotational modes, and unstable hinge formation. 1717 LAVROV, IV ROMANCHUK, VE SNORODINOV,MI Use of radioisotope methods for investigation of submarine deposits .2F,IR.
