The invention discloses a safe hoisting analysis method of an underground diaphragm wall reinforcement cage truck crane near a high-voltage line, and belongs to the technical field of underground diaphragm wall construction in foundation pit engineering support. The safe hoisting analysis method mainly comprises the steps of data collection and analysis, weight calculation of the underground diaphragm wall reinforcement cage, hoisting calculation, hoisting machinery type selection, model diagram drawing, station simulation and hoisting method determination. According to the method, hoisting machinery in a proper range is screened out through calculation of a reinforcement cage and hoisting stress, hoisting machinery stations are preliminarily screened in combination with the safety distance of the high-voltage line and the position of the high-voltage line, a model is drawn to simulate the relative position, and the electric shock danger coefficient of the high-voltage line is reduced to the minimum; and the device is suitable for construction operation of the diaphragm wall in foundation pit engineering support.
