【摘要】 将释放荷载看作时间函数,用解析方法分析推演了圆形隧洞围岩与支护结构之间相互作用的时效规律,更好地反映了工作面空间效应的影响,对合理设计永久性支护结构具有指导意义。更多还原

【Abstract】 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.更多还原
