摘　　要：介绍手持普通相机监测隧道洞室位移的近景摄影测量。该技术测点多、外业操作简便,不需专用设备,能全面、客观地测定大变形隧道洞室各点的三维位移矢量。在实际应用中与机械式收敛计的量测结果进行比较,该技术反映隧道洞室位移更具客观性。A new method is presented for monitoring the deformation of tunnel with amateur camera（non-metric camera）. The method can easily and really measure 3D deformation values of tnany survey points of tunnel. It does not need any fixed exposure station or survey control point, and the method is not restricted by site conditions. At two suitable positions and more positions, the camera takes pictures against observation points, then these photographs are input to computer and the photo points are measured by computer to calculate 3D coordinates of all survey points. The analysis of deformation is processed by using 3D coordinates. The mean square error of 3D monitoring deformation is within _ 2 mm. The results measured by new method have been compared with the values measured by mechanical convergence meter, which can provide reliable information for the safety of tunnel support structure.
