Abstract


In this paper, rock viscoelastic medium model to study the viscoelastic rheological characteristics of surrounding rock are given in supporting counter- force constants including viscoelastic characteristic curve of rock -time effect of closed form solution , and discusses supporting opportunity in rock - bolting system 's role and representation methods , combined with the actual calculated and analyzed . Argillaceous soft rock as the prototype , the preparation of soft rock similar material and rheological properties of the test . Through modification of the plane strain model loading device used in the preparation of self- similar material soft rock , experimental study of soft rock roadway plane strain model of stress and deformation characteristics , achieved some measured data , through the promotion of the prototype of the theoretical analysis results are authentication. The paper concludes for engineering design and construction and other personnel of the reference .
