摘要
This paper combines the extension theory methods with the surrounding rock classification for high geostress tunnel.It establishes the method of rock classification for high geostress tunnel based on extension theory. Bases on matter-element theory,extension set and dependent function calculation to establish the material element model of the surrounding rock classification.It follows the degree of association calculations for the actual rock classification.The final rock classification can determined.
