Research Abstract

This study has carried out a trial production of the new base friction apparatus for underground utilization at a depth, though current base friction apparatus has been limited for fitting within shallow depth, and some model tests by using it.
In the newly developed base friction apparatus, friction force on the plate and external forces by jacks and rubber bags in vertical and horizontal directions, respectively, are simultaneously applied to produce a high stress field. This development of the new base friction apparatus enables a quantitative research of the deep underground. The picture analyzing system for model test has also developed. Record of experimental result is done optically with a camera and a video floppy recording system with a high accuracy.
Nextly, the experimental results of the scale model tests on underground opening and slope consisting of homogeneous and discontinuious rock masses are compared with theoretical analysis and clarify the mechanisms of instability of rock mass.
