| 摘 要： | 在分析松软破碎带中巷道围岩的稳定性和支护影响因素的基础上,借助于注浆改善围岩特性并结合锚杆支护,通过现场实测、理论分析和FLAC数值模拟相结合的方法,确定了松软破碎带中的巷道围岩注浆深度、浆液比例和注浆孔间距等加固参数。研究结果对类似条件下的巷道的支护具有一定的指导意义。

| Abstract: | The stress,support factors and lithology of the soft,develeped tectonic zone were analyzed.The combination of grouting reinforcement and bolting was adopted to determine the grouting reinforcement parameters,including grouting depth,grout mix ratio and grouting hole interal,by in-situ measurement,theoretical analysis and FLAC numerical simulation.The research provides some guidance for supporting of tunnel in similar environment. |
