VISCO-ELASTICAL ANALYSIS ON INTERACTION BETWEEN SUPPOTING STRUCTURE AND SURROUNDING ROCKS OF CIRCLE TUNNEL
圆形洞室围岩与结构相互作用的粘弹性解析

Regarding released load as the function of time,the interaction between supporting structure and surrounding rocks of circle tunnel with time is deduced through analytic method. The study result of this paper is significant for designing permanent of supporting structure to reflect the spacial effect of working face.
