Large-span continuous beam hanging basket cantilever cast-in-place beam measuring method

The invention discloses a large-span continuous beam hanging basket cantilever cast-in-place beam measuring method, which comprises the following steps of: arranging two encrypted measuring points on the top surface of a poured segmental beam where a hanging basket is positioned, and setting out and adjusting a front template; under the condition that the temperature gradient of the beam body is zero or close to zero, accurately measuring the coordinates and elevation values of the encrypted measurement points at the end of the continuous beam through a construction control network; on the basis of the design drawing and the monitoring instruction, calculating a target value of the front-end template in the state that the beam body temperature gradient is zero; setting a total station by using the encrypted measurement points at the beam end, and measuring and adjusting the template according to the target value calculated in the previous step; and checking the axis deflection angle and the relative height di
