中文摘要：
以重庆轨道交通六号线二期工程曹家湾车站为例,对拱顶下沉、隧道周边收敛位移进行监控量测,利用Origin软件实现对量测数据的绘图、非线性拟合等处理,可以预测隧道拱顶沉降的最终值为11 mm,隧道的周边收敛为8 mm,采用围岩稳定性判断标准对监测数据进行回归分析,可以得到隧道围岩是处于安全状态,因此通过对量测数据的分析处理,可以掌握围岩稳定性的变化规律。
英文摘要：
Taking Caojiawang station in chongqing for example, vault crown settlement and peripheral convergence of tunnel were monitored, and the monitoring data was processed by using logarithmic function fitting, it was predicted that the final value of the tunnel vault subsidence is 11 mm and the peripheral convergence of the tunnel is 8 ram, The stability criterion of surrounding rock was adopted to regression analysis on monitoring data,the tunnel surrounding rock was in a safe state, so monitoring data was processed, variation of stability of surrounding rock was mastered.
