Publ Rotterd=-m: A A Balkema, 1980 Describes the results of a series of tests on socketed bored piles in strong shale at Westmead, near Sydney, Australia. Discusses the effect of rock defects and c~npares the results with other data. Also discusses the question of allowable defects ~ the field control of socket lengths. 812136 ~,~_ASI3R~ENf AND ~ALYSIS OF LO~D T R A N ~ E R FRCM A CAISSON TO ITS ROCK SOCkeT Bauer, G E Proc International Conference on Structural Foundations on Rock, Sydney, 7-9 May 19~0, P235-240. Publ Rotterdam: A A Balkema, 1980 Describes a project where cast-in-place caissons (piles) were used to support heavily loaded shear walls of an 8-storey building, and discusses a finite element investigation of the load transfer mechanism. ~12137 DESIGN A_ND CONSTRUCTION OF ROCK CAISSONS Gill, S A ?roc International Conference on Structural Foundations on Rock, Sytiney, 7-9 May 1980, P241-252. Publ Rotterdam: A A Balkema, 1980 Gives design procedures and discusses some constructlon problems for rock caissons (large diameter piles). Criteria used for inspection of rock foundations containing seams of weaker materials and their theoretical basis are also discussed. 812138 _~ORETICAL STUDY OF PILE-ROCK sOCKET BEHAVIOUR Rove, R K; Pel!s, P J N Proc International Conference on Structural Foundations on Rock, Sydney, 7-9 May 1980, P253-264. Publ Rotterdam: A A Balkema, 1980 Presents a finite element model and uses it to study the factcrs affecting the response of an isolated socket. Gives the results in the form of influence charts which provide an estimate of the pile head settlement, the load transfer to the pile tip and the degree of shear mobilisation along the socket. 812139 ULTD&~TE TENSILE LOADS OF BORED INT.O SANDSTONE ROCK W'ebb, D L; Davies, P Proc International Conference Foundations on Rock, Sydney, ~65-270.

Publ Rotterdam: A A Balkema, 1980 The method satisfies both allowable settlement and strength criteria, and accommodates the general non-linear load deformation characteristics observed for socketed piles in weak rock. Side res~star~e, base resistance or both can be incorporated. The application of the method is discussed and examples ~re given. The method was developed for Melbourne m~dstone but is consldered applicable to other rock types. 812146 RESULTS OF TESTS TO Dz±~MTNE ~4/%~T R E S I S T ~ E OF ROCK-SOCkkT~u DRILLED PIERs Hc&'vath, R G; Kenney, T C; Trow, W A Proc Inter~tlori~l Conference on o~tructural Foundations on Rock, Sydney, 7-9 May 1980, P349-361.
