K. Aoki et Y. Shiogama, GEOENGINEERING TECHNIQUES USED IN THE CONSTRUCTION OF UNDERGROUND OPENINGS IN JOINTED ROCKS, Engineering geology, 35(3-4), 1993, pp. 167-173
Examples of underground openings used for pumped storage hydroelectric
power stations and storage facilities for crude oil in Japan are desc
ribed. In these examples the observational construction technique is i
mportant to compensate for missing data in the preliminary surveys. So
me new drilling and assessment techniques that have been developed are
also introduced.
