摘要
为了解决高压富水环境下断层破碎带松散破碎岩体的灾后加固难题,采用注浆加固法对围岩进行处治.基于地震波折射层析法,探查灾害区域围岩松动圈范围,采用中隔岩柱与右洞联合注浆处治的方法对围岩进行封堵及加固.结果表明:根据断层突水突泥后的围岩松动圈探测结论对围岩的注浆加固处治取得了良好的效果,围岩性质、涌水量及位移均得到明显改善,其研究方法和结果对类似工程研究具有一定的指导和借鉴意义.
In order to solve the problem of post-disaster reinforcement of loosely fractured rock mass in fault fractured zone under high pressure and water-rich environment,grouting reinforcement method is used to treat surrounding rock.Based on the seismic wave refraction tomography,the scope of surrounding rock loosening zone was detected in disaster area.By drilling chamber,combined the middle rock column and the right tunnel grouting treatment method was used to block and strengthen the surrounding rock.The results indicate that according to the detection conclusion of surrounding rock loosening zone after water inrush and mud inrush from faults,the grouting reinforcement treatment of surrounding rock has achieved good results.Surrounding rock properties,water inflow and displacement have significantly improved.The research methods and the results make certain guiding significance to the practical engineering.
