Abstract

The invention provides landslide underwater deformation feature transfer monitoring equipment and method, a buoy is mounted on a floater, and a positioning unit is mounted on the buoy and used for acquiring coordinate data of the buoy; the anchor is used for being fixed in an underwater gliding body; the shell is hollow and installed on the buoy, the winding hub is installed in the shell through the winding wheel shaft in an axial rotation mode, one end of the pull wire is wound around the winding hub, the other end of the pull wire penetrates through the shell to be connected with the anchor, and the driving mechanism drives the winding hub to rotate in the axial direction. The stay wire length measuring unit measures the winding and unwinding length of a stay wire, the stay wire posture measuring unit measures the posture of the stay wire, and the stay wire tightness state obtaining unit obtains the tightness state of the stay wire. The change data of the underwater glide body is obtained through monitoring, and the spatial state change of an underwater deformation point is calculated through inversion in combination with the positioning of a water surface buoy, so that the error is reduced; surge interference caused by traffic factors such as the dynamic flow velocity of Yangtze River water flow and ships is avoided, and the accuracy of displacement monitoring of underwater glide body monitoring points is improved.

Description

technical field [0001] The invention relates to the technical field of landslide geological disaster monitoring and prevention, in particular to a landslide underwater deformation feature transfer monitoring device and method. Background technique [0002] There are many reservoirs and dams in our country, most of which are located in the western regions with high altitude, high seismic intensity and complicated geological conditions, and landslides on the banks of the reservoirs are particularly developed. Landslide monitoring technology is an important method to understand the evolution law of landslide deformation and identify its evolution stage, and it is also an important basis for early warning and prevention of landslides, guaranteeing engineering construction and people's safety. [0003] The underwater deformation characteristics of reservoir bank landslides are an important part of landslide deformation. Affected by the rise and fall of the water level of the res...
