| Abstract: | An underground engineering design requires a determination of mechanics coefficient for rock. A displacement reverse-analysis is used to reversely derive its instant elastic modulus and earth stress according to the initial condition of displacement surrounding the rock when an underground round tunnel is dug. A general formula is given of four kinds of viscous elastic mechanics models. |
| Keywords: | displacement reverse-analysis initial displacement instant elastic modulus lateral pressure coefficient |
