| Abstract: | Using a combined Rheological model, this paper presents a solution to the time-effect deformation around unlined underground opening under two-dimensional crustal stress field in visco-elastic foundation. And in the case of three-dimensional crustal stress field, a formula to compute the deformation is given by using the equivalent initiative crustal stress.By measurement of radial displacement the method of inverse analysis of the elastic and creep displacement and its initiative and final value is introduced, and examples of engineering practice are given as well. |
