The invention belongs to the field of concrete dam construction organization, and relates to an arch dam concrete cable crane hoisting track prediction method, which comprises the following steps: 1) constructing a space coordinate system, and determining a space positioning node of a cable crane; 2) acquiring real-time position information of a spatial positioning node of the cable crane by using a sensor; 3) performing filtering and noise reduction preprocessing on the real-time position information of the spatial positioning node of the cable crane by using Kalman filtering; 4) calculating the preprocessed real-time position information of the spatial positioning nodes of the cable crane, and obtaining time sequence motion state parameters of the cable crane; 5) constructing a cable crane trolley-lifting rope-hanging cage system dynamics model, and 6) predicting the swing angle of the cable crane hanging cage based on the cable crane trolley-lifting rope-hanging cage system dynamics model and obtaining the motion trail of the hanging cage. The arch dam concrete cable crane hoisting track prediction method can improve prediction precision.
