摘要
Abstract
The lining of underground hydraulic tunnel serves as a permanent support structure,playing a crucial role in ensuring the long-term safe operation of the tunnel.Under normal conditions,the tunnel lining and surrounding rock are tightly integrated and work together as a unified system.However,the voids behind the lining or structural defects in the surrounding rock can reduce the tunnel's load-bearing capacity against internal and external pressures,thereby compromising its safety and stability.Taking a certain water conservancy hub project in Xinjiang as an example,the high-density seismic imaging was adopted to detect the surrounding rock structure behind the lining of a collapsed section of the hydraulic tunnel.Through the analysis of the high-density seismic imaging profiles and borehole verification,the effectiveness and feasibility of this method for detecting defects in tunnel surrounding rock were demonstrated.The approach achieved good detection results and provided data support for subsequent grouting treatment.关键词
