The teats have been carried out on a 50 m long strip of lamd; Two boreholes should give the following information: i. Groumd movement on the surface and umdergroumd; 2. Deformation and stresses in the lining of the tunnel.The test results have shcwn settlements and stresses and it proved impossible to forecast the fu ture rock behaviour; From the l~actical point of view, it became evident that the Austrian tunnelling method can be t~sed even in difficult geological conditions.

PROCeeD. 2 CONGRESS, INTERNAT. SOC. ROCK MECH. BELGRAD, I~70,V4, i~74, P252-253. Bc~ehole dilatomet~rs are used to measure the deformation of a rock mass; The wall of a rock borehole is loaded by hydraulic pressure and the radial deformation is estimated. Assuming that the rock is a homogeneous body, to which the elastic theory can be applied, it is possible to estimate the value of the d~fc~mation modulus for the measured radial borahole. The principle of the borehole dilatometer is given. The author recommends stamdardlsation of bcrehole diameters in order to compare the values of measurements on an international scale. 813 DESAI, C S Conlnents on paper~ Finite element amalysis of elastic plastic problems in the mechanics of geologic media.

It is difficult to establish an equilibrating stress function as compared to choosimg a compatible displacement for,,,lation. Regarding associated variational principles for problems involvlmg coupling between rock or soil deformations amd the behaviour of pore fluids~ the mixed variational principle of Reissner amd Gurtin for initial ~alue problems has been successfully employed in recent years. 814 WITTKE,W INST.

The doorstopper proved to be more convenient in field teatimg of stresses. The doorstopper cannot be used where appreciable amounts of water flow into the bore- hole. The interpretation of results, which are sometimes scattered, is best dons by employlmg a statistical method which gives not only an ur~iased estimate of the stress components, but also an estimate of their variances, covariances and con- fidence levels. A computer program SASM can be used in this method; Sur face s t ructures Embankments and embankment dams 817 TRUDINGER, JP Engineering geology of the Kargaroo Creek dam; FigsjTabls. GEOL.

This paper considers data fc~ a building at the New York World's Falr~ which revealed a small but definite amount of foundation rocking, in dyr~mic shaking tests~ an effect not analysed in the original study, The inclusion of rocking into the dynamic analysis is shown to improve the agreement between ~redicted and observed frequences. The effect of foundation swaying is also ar~lysed, leading to a conclusion concerning the magnltude of the damping associated with swaying. 8~6 VOGEL~ C BARACOS, A DA SILVEIRA~ I Analysis of ultimate loads of shallow four~lations, Discussions of paper by A.S.
