Experimental Simulation of Rheological Large Deformation Problems by use of Meterials with Memory

in this peper, the experimental simulahon of rheological largely deformabletheies is carried out by means of grid method and meterials with ability of memory. As a practicalexample in engineering, the theological large deformation of a tunnel surrounded by soft rocks isinvestgnted. Analysis is based on the finite deformation theory. The results, obtained throughcompater, indicate that these methods and technology are nimble, reliable and practical.
