... by VicRoads in 1995 to enable an earlier opening of a tourist road located in steep mountainous terrain, which had been closed by up to 53 landslips, just prior to the peak tourist season. Had they been repaired using conventional treatments, the road would have been closed for up to six months, and would...

Toutefois, dans certains secteurs, ces ruptures prennent des formes singulières par leur brutalite et l'ampleur de la zone affectee: ce sont les coups de terrains ou "rockbursts" de la...

The fact is, the work was delayed one Year to complete by unexpected engi- ne~ring geological problems, encountered ~a1nly in digging the tunnels, which lorm nearl~ one-third of the total ength of the very railway. The failure of KU-Yin Tunnel is one of the cases and is to be described...

... INTRODUCTION It is proposed here to discuss some case histories of artificial crustal disturbances in fractured rook mass. These case histories involve two oases of reservoir induced seismicity at Idukki and Kadana reservoirs, both situated in fractured rook terrain, but in different tectonic...

..., and in many cases after the exe- cution of other investigation works, eva- luation by on site and desk top studies of the terrain is undertaken. This may be by the observation of exposures, terrain evaluation using aerial photo- graphic interpretation, the sinking of shallow trial pits and probes...
