STUDY ON VISCOELASTIC MACHANICAL MODEL RECOGNITION OF ROCK MASS AND METHODS OF PARAMETER INVERSION ANALYSIS

Based on the recent progress in the inversion analysis methods viscoelasitc displace ment of the circular and noncircular tunnel surrounding rock,fiveviscoelastic mechanical model recognitions and parameter inversion theorems are put forward according to the inversive regularities of mechanical parameters analyitical solution of the tunnel sur rounding rock, and some computational examples and practical instances are given to make the necessary examination of the theorems obtained here.
