The invention discloses a method for measuring and calculating a forced deflection angle of a cargo boom in a luffing process of a tower crane, which comprises the following steps of: firstly, acquiring basic parameters of the tower crane, then acquiring operation state parameters of the tower crane in luffing motion, analyzing system kinetic energy and potential energy of the tower crane, and calculating the forced deflection angle of the cargo boom in the luffing process. And constructing a systematic Lagrange equation according to the law of conservation of energy, solving and simplifying the Lagrange equation, carrying out Laplace transformation, and solving to obtain the forced deflection angle of the cargo boom. According to the method, the forced deflection angle of the cargo boom in the variable-amplitude motion can be quickly measured and calculated in real time by acquiring the basic parameters of the tower crane and the operation state parameters of the tower crane in the variable-amplitude motion, and additional measuring instruments are not needed; and a foundation is laid for a subsequent tower crane to quickly eliminate the forced deflection angle of the cargo boom.
