摘要

为了获得低山岭隧道施工过程中围岩结构位移和支护结构内力随时间的变化规律，本文以西山隧道工程为背景。在隧道掘进过程中，对隧道周边位移、地表沉降、钢拱架内力、两层支护间压力等进行动态监测。根据上述监测和测量数据，通过监测数据分析和非线性回归拟合，得到预测趋势曲线，得出隧道各种围岩的位移变化规律和特征，确保施工安全和支护结构的稳定性要求，为二次衬砌施工提供合理的契机。

Construction monitoring and analysis of low mountain ridge tunnel

In order to obtain the change rule of surrounding rock structure displacement and supporting structure internal force with time during the construction of the low mountain ridge tunnel, this paper relies on the Xishan Tunnel Project as the background. During tunneling, the displacement around the tunnel, the subsidence of the surface, the internal force of the steel arch and the pressure between the two layers of support are monitored dynamically. According to the above monitoring and measurement data, and the monitoring data analysis and nonlinear regression fitting, the predicted trend curve is obtained, the displacement change rules and characteristics of various surrounding rocks of the tunnel are obtained, to ensure the construction safety and stability requirements of supporting structure, and to provide a reasonable opportunity for the construction of secondary lining.
