摘要
以乐业隧道的实际案例为基础,综合分析了工程地质特征、地应力条件及地下水条件,采用超前地质预报的物探方法,结合现场试验与实测数据,对注浆治理机制进行深入研究。为此,提出一种结合“超前探测+注浆加固+结构优化”隧道变形治理方案,经过现场监测,变形量明显减小,拱顶沉降及水平收敛幅度均降低,并通过调整围岩支护参数和施工方法,从源头降低变形风险,为类似工程建设提供可参考技术方案和经验支持。
Using the Leye Tunnel as a case study,this study comprehensively analyzes the engineering geological characteristics,ground stress conditions,and groundwater conditions.Advanced geological prediction methods based on geophysical prospecting,combined with field tests and measured data,were utilized to conduct an in-depth investigation of the grouting treatment mechanism.Consequently,a comprehensive treatment approach integrating“advance detection+grouting reinforcement+structural optimization”was proposed.Field monitoring results indicated a significant reduction in deformation,with both arch roof settlement and horizontal convergence effectively mitigated.Additionally,deformation risks were minimized at the source through adjustments to surrounding rock support parameters and construction methods.This study provides a technical reference and practical experience for the construction of similar projects.
