Present sealing technology and sealing materials are reviewed in terms of the particular meeds of vault sealing. Discusses vault grouting, borehole sealing, buffer packing and backfilling. 816077 APPLICATION OF 'NO TENSION' AY~ALYSIS TO FISSURE DEVELOPMENT IN PLUTONIC ROCK ABOVE i NUCLEAR WASTE VAULT Osnes, J D; Brandshaug, T In: Ur,iergrourzl Rock Engineering (Papers to 13th Canadian Rock Mechanics Symposium, Toronto, 28-29 May 1980), P193-197. Publ Montreal: CIMM, 1980 A finite element analysis of a region surrounilug a nuclear waste vault in granite or gabbro was performed. The rock was assumed to be a material possessing zero tensile strength, and a no tension load transfer technique was employed in conjunction with a subsequent plasticity armlysls based on the Mohr-Coulomb failure criterion. Regions in which Joints amd fissures may open to relieve stress were determined. Such regions undergo changes in permeability. 816078 IMPORTANCE OF JOINT BEKAVIOUR ON POTENTIAL WATER INFLGW INTO UNDERGROUND STRUCTURES - AN ANALYTICAL APPROACH Bawden, W F; Curran, J H; Roeglers, J C In: Underground Rock Er~ineerlng (Pa~ers to 13th Canadian Rock Mechanics Symlx~sium, Toronto, 28-29 May 1980), P211-ZIT. Publ Montreal : C ~ N , 1980 Utilizes models to study flow in dilatant fractures and attempts to define the rathe of influence of fracture deformation on coniuctivity and the limitations of the discrete al~roach. The model is based on the coupling of dilatamcy and conductivity. Results indicate that dilatamcy may be the central parameter affecting conductivity in deformable fracture flow. The implications of the results on the design amd performance of a number of field investigations ani engineering structures are discussed. 816079 PRESSURES ON BURIED PIPES DUE TO REVISED KB LOADING Nath, P Transport and Road Research LaboratcaV, laboratory report 977, 1981, 22P The loads on pipes buried unier main roads due to the revised HB loading are given in this report, and are compared with those due to the former HB loading ani also with those obtained from the 'Simplified Tables' currently used to design buried rigid pipes. A cccrputer program based on the classical Boussinesq solution was developed for the present calculations in which the effects of the position of the HB vehicle relative to the pipe, the non-unlformity of the pressure distribution at shallow del~ths, and of varying the length of the pipe over which the average pressure is determined were considered.

A description of new developments in techniques ~ equipment is unlertaken. These include various methods of improving rock cutting ability arz[ e c o n c ~ by the application of new tool materials and accessories, different materials anl techniques for roadway sttwpcrt and support setting, and devices and machines which are aimed at improving available time for cutting and loading.
