The invention belongs to the field of super-large space building construction. In order to solve the problem of safety hidden danger due to lack of safety monitoring of super-high formwork frame and failure of stress stability during construction of super-high formwork frame, the invention provides an in-situ monitoring method for stability of super-high formwork frame, which is based on total station and reflecting device to realize monitoring, and reflecting device is installed on target monitoring pole of super-high formwork body. For monitoring points, the three-dimensional coordinates of monitoring points are measured by total station to determine the stability of early warning superelevation. The invention is based on the intelligent total station positioning technology, fixing the reflective film at the required parts of the identified poles, using the automatic target recognition system, completing the target search, accurate alignment and automatic observation, obtaining the deformation data of the frame with the change of the upper load in real time, and early warning the stability state of the super-high frame in advance, which can effectively avoid the occurrence of safety accidents, and has remarkable early warning effect. It can be used in superelevated frames of different structural forms and has a wide range of applications.
