摘要
建立了双向不等压锚注软岩巷道计算模型,将巷道围岩分为锚注加固区和未注围岩区,分别采用不同的粘弹性模型,解出锚注软岩巷道围岩应力、位移粘弹性解,同实际观测得到的锚注软岩巷道位移曲线作比较,证明其粘弹性解是正确的。研究结果对软岩巷道锚注设计具有一定的参考意义。
The computing models of bolt-grouting support for two-way unequal roadways in soft rocks are set up. Rock strata around roadway are divided into reinforced zone of bolt-grouting support and unreinforced zone,in which different viscoelastic models are used and the stress-displacement relationship of roadways is derived. The viscoelastic solution is reasonable compared with practical observed displacement curve of bolt-grouting supported roadways in soft rocks.
