自由设站监测深基坑支护结构变形的新方法,使用经纬仪或电子经纬仪测量变形点的水平角和竖直角,自由测站,不需要量取仪器高度,外业操作简便,对施工影响小,不受施工现场场地狭窄的限制,能取得较好的三维位移监测精度,为深基坑支护结构提供可靠的变形信息。 Freely set up a new method for monitoring the deformation of deep foundation pit supporting structure, use theodolite or electronic theodolite to measure the horizontal and vertical angles of deformation points, free measuring station, no need to take the instrument height, Small, not limited by the narrow site construction site, can achieve better accuracy of three-dimensional displacement monitoring, deep excavation supporting structure to provide reliable deformation information.
