摘要
采用钻孔内窥仪完成了围岩松动圈分布规律现场测试,基于松动圈理论给出了文家坡1#运输岩石巷道支护设计,建立了巷道围岩稳定性评价FLAC计算模型,完成了巷道围岩变形规律FLAC预测分析,制定了围岩变形现场监测方案。
Completed the distribution field test of surrounding rock loose circle by the borehole endoscope, design the support of Wen Jia-po No.1 transport roadway by the theory of rock loose circle,established the FLAC model on the evaluation of stability of surrounding rock of roadway, and completed the prediction and analysis of FLAC of surrounding rock deformation law,established the filed monitoring scheme of the surrounding rock deformation.
