摘　　要：针对软岩隧道变形监测问题,本研究依托武都西隧道,选取监测断面布置测点,进行拱顶沉降和周边收敛监测。其间利用监测数据绘制拱顶下沉及周边收敛的位移、速率曲线,研究了拱顶沉降和周边收敛的变形规律,并对实测数据进行拟合,获得曲线拟合方程,初步预测变形稳定时的位移值,为类似隧道变形监测及变形规律研究提供借鉴。Aiming at the problem of soft rock tunnel deformation monitoring,this study relied on the Wuduxi Tunnel,selected the monitoring section to arrange the measuring points,and monitored the settlement of the vault and the surrounding convergence.In the meantime,the monitoring data was used to draw the displacement and velocity curves of the dome subsidence and the surrounding convergence,and the deformation laws of the dome subsidence and surrounding convergence were studied,and the measured data were fitted to obtain the curve fitting equation and preliminarily predict the displacement value when the deformation was stable,so as to provide reference for similar tunnel deformation monitoring and deformation law research.
