Abstract:In the process of bridge construction or operation management, the verticality of piers is one of the important control factors. On the basis of expounding the traditional measurement method of piers, a fast measurement method of pier verticality based on vector method is put forward by using 3D laser scanning technology. Combined with the actual measurement results of piers, it is concluded that the measurement results of this method are consistent with those of the traditional methods, and the measurement has high precision, which has a certain application prospect for the verticality measurement of bridge pier or similar high-rise buildings.
