摘要
认为软岩巷道稳定性应采用动态支护的观点分析．用巷道周边位移表达的损伤因子来描述围岩阶段性变形特征及破坏过程，分析与之对应的围岩强度弱化规律，在此基础上提出了喷锚注分阶段加固技术，并对合理滞后注浆时间的确定进行了研究．最后。
The
stability of soft rock roadway should be analyzed in the view of dynamic supporting. Damage
factor expressed in the displacement of roadway wall is used to describe the characteristic of
stage deformation of surrounding rock of roadways and its damage process. And the
corresponding regularity of rock strength weakening is investigated. Based on the above, a
staged reinforcement technology of shotcreting bolting grouting for greatly deformed softrock
roadways is put forward, and the rational opportunity of delayed grouting is discussed. Finally,
an engineering example is given.
