Abstract
The invention provides a soft soil roadbed settlement high-precision monitoring method. Settlement in a roadbed is monitored in a camera shooting mode, a novel roadbed settlement monitoring device is designed, a body of the device is composed of a settlement plate, a hollow pipe, an inner-layer PVC pipe and an outer-layer PVC pipe, wherein the settlement plate and the inner-layer PVC pipe are connected through the hollow pipe, a range allowing sliding is reserved between the inner-layer PVC pipe and the outer-layer PVC pipe, the distance from the settlement plate to the outer-layer PVC pipe is the measuring range of the device and can be selected according to the height of a measured roadbed, a placing frame is arranged in the inner-layer PVC pipe, two penetrating holes are formed in the bottom of the inner-layer PVC pipe, and a stay wire passes through the penetrating hole, bypasses the placing frame, passes through the other penetrating hole and is connected with a counter weight. The stay wire is straightened, then the camera of the inner-layer PVC pipe is used for monitoring, data are transmitted through the cable, and the shooting interval is set to achieve the purpose of real-time monitoring.
