Abstract: 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 .
