Kinematic analysis of blocks in tunnel on the basis of discontinuities.
This paper demonstrates the advantages of using stereographic projections in kinematic analysis of rock blocks in excavation surface. The stereographic method is completed by planes and poles as points and lines on the horizontal surface and the block kinematic behavioral analysis is investigated...

| description | This paper demonstrates the advantages of using stereographic projections in kinematic analysis of
rock blocks in excavation surface. The stereographic method is completed by planes and poles as
points and lines on the horizontal surface and the block kinematic behavioral analysis is investigated in
a rock free face subsequently. A block is considered to be an instable one when the intersection lines
fall into the critical zone, this area is defined through the relationship between the friction angle of the
stone mass and the slope of the free face respectively. It is possible to determine the movement of the
blocks on the basis of the discontinuity position before any collapse or sliding happens. |
