巷道围岩变形规律依赖于锚杆支护参数变化的流变分析

Rheology Analysis of Adjoining Rock of Roadway Relying on Bolting Parameters

针对锚固岩体的细观组构不同于原岩体的特点，分别赋予它们不同的本构模型，采用相应原理，导出了描杆支护圆断面巷道围岩流变的粘弹性解，分析了锚杆密度、长度变化时，巷道围岩的变形规律及其影响程度．对工程岩体的力学参数进行等效处理后，可利用该方法指导支护设计．

In this paper, for bolted and original rock mass, different constitutive models are give according to their meso compositions, by using of corresponding principle, the viscoelastic solutions of bolted circular roadway have been gotten, and the deformation rule of roadway relying on density or length of bolts has been analysed. This method can be used to guide support design after mechanical parameters are equivelently conversed in engineering.
