High rockfill dam body deformation monitoring method

The invention relates to a high rockfill dam body deformation monitoring method. The method comprises the steps of: connecting an array displacement meter with deformation monitoring robots, wherein each monitoring robot forms a monitoring unit, and the deformation monitoring robots are connected with a data processing platform through wireless transmission, and the plurality of monitoring units are connected in order to form monitoring assemblies; selecting a plurality of horizontally-arranged surfaces in the height direction of a dam body, arranging first monitoring assemblies parallel to the downstream direction of the river and second monitoring assemblies parallel to the width direction of the river on the horizontally-arranged surfaces, and then arranging a plurality of sets of thirdmonitoring assemblies at intervals are arranged in the vertical direction; and receiving formation information at each monitoring point by the data processing platform, performing calculation according to the received deform
