This Paper gives an analytical solution of the interaction between confining rock and lining in viscoelastic-plastic rock media for the axia11y symmetrical case
The complex conditions due to long-term plastic limitation and existence of the deteriorated plastic region are specially considered
It indicates that loading on lining relates to range of plastic region
lining time and a series of physical
mechanical
geometrical factors concerning confining rock and lining
The loading on lining can be determined quantitatively
and the most reasonable lining time is derived. Several calculation examples are given herein .
