摘要
为解决在富水隧道内施工时的围岩稳定问题,确保施工安全,通过数值模拟探讨了注浆技术对隧道拱顶沉降、水平收敛、拱底隆起、地下水位变化等多项监测指标的影响。为验证数值模拟结果,通过自动化监测系统获取了现场监测数据,将实测值与模拟值进行了对比分析。结果表明,实测值与模拟值具有较好的吻合度,验证了数值模拟分析的精确性,说明注浆加固对富水地质中围岩变形及地下水渗流具有良好的控制效果。
In order to solve the surrounding rock stability problem during construction in water-rich tunnels and ensure the construction safety,the influence of grouting technology on monitoring indexes such as tunnel arch top settlement,horizontal convergence,arch bottom uplift,and groundwater level variation was explored through numerical simulation.In order to verify the numerical simulation results,field monitoring data were obtained through an automated monitoring system,and the measured values were compared and analyzed with the simulated values.The results show that the measured values and the simulated values have a good degree of consistency,which verifies the accuracy of the numerical simulation analysis and shows that the grouting reinforcement has a good control effect on the surrounding rock deformation and groundwater seepage in the water-rich geology.
