Shock pressure of tsunami bore on a wall-shaped gate is investigated on the basis of an assumption that a surge caused by a dam-breaking can be made to s1~11ate a tsunami surge in front of the gate in an estuary.

The behaviour of the horizontal dam arch was examined for more types of discontinua at equal conditions. The e x . amination was done by means of geostatical models with respect to the limit bearing capacity, displacement of arch support, contact bearing pressures on supports, displacement of various points of rocky msss as well as to the pressure distribution in the very discontinuum. The paper gives a short description of characteristic results of examination. Auth. 130. SCHN]~I~,NJ The Emosson arch dam. 14F,7T,7R. WATER POWER,V26, N3,197~, P77-87.

PM)C.3RD. CONGRESS INT.SOC.BOCK ~,~"H.SEPT.1974, D ~ V ~ % U S A , NAT.ACAD.SCI.VI,PART A,1974,PSI7-863 . The report reviews the uses of physical models for testing mechanical properties of rock foundations or slope systenm. The conditions for mechanical similitude between the IEototype and model, and general considers~ions on the processes of deformation and failure are discussed.A Practical example of gsomechsmical models is given. Two dimensional models; the instability of slopes, sliding and collapse; and centifugal models are also reviewed. 135. ROCHA, M TECH .UNIV.

The report presents the methods thought advisable for characterizing foundation rock-masses of concrete dams, the testing procedures to be followed and how to express the results for their application in the design. The structure of the rock-mass, deformability of the foundat. ions, the strength of the foundations and the initial state of stress in the foundation rock.mass are discussed in four ma~or sections. 136. GALLICO, A ELC- ELECT~CONSULT, MILAN, I A contribution to the design of foundation systen~ for arch dsm~. IOF,2T. WATER POW~,V26, NI0,1974, P323-329. A brief review of practical acco~lishments in the desi@a and construction of arch dams is presented. Eight structures at hydro sites in Mexico, Japan, South America, Taiwen and the USSR are considered to illustrate these features. 137.

The plane strain model of a rigid building foundation embedded below the surface of an elastic half space and vibrating freely, is used to derive equations of motion for free vibrations of the foundation. 138. POUIOS,HG load-deflection prediction for laterally loaded piles. 21F, 5T,22R. AUSTRAL. GEOMECH. J .V93,NI, 1973, PI- 8. A series of solutions are presented in graphical form which enable the load-deflection behaviour to failure, of a laterall~.loaded pile to be calculated. An eccen. trically-loaded free-head floating pile is considered for soil with constant Young's Modulus and yield pressure, and soil with Young's Modulus and yield pressure in. creasing linearly with depth. Good agreement is found between the measured load-deflection curves for a series of tests on model piles in clay, and those predicted from the theoretical curves. 139.
