During the operation of tunnel escalators risks of passenger injury are large. To a great extent it is connected with the unduly technical state of the escalator itself. The technical state proceedings is often complicated by the control necessity of latent defects. Especially it is actual for the fatigue damage control of structural sections. Now scientists have a large data volume of this control by means of the coercive force meter in respect of metal structures of tunnel escalators installed in underground station of Saint Petersburg city. During the realization of the control procedure scientists have faced to the necessity of the foundation of control points of fatigue damages of metal structures of the escalator because the traditional approach based on the subjective experience can be not enough precise. Therefore it was suggested to determine such points on the basis of 3D modeling in the automated projecting system. In this work such modeling was realized that has allowed determining a new set of control points. Further control results of fatigue damages of metal structures of one of tunnel escalators at points installed on the basis of the traditional approach and by means of 3D modeling were compared between each other. It enabled to suppose that the suggested method can be effective. The mathematical processing of received data has allowed determining the volume of preliminary research for the adequacy evaluation of the 3D modeling for needs of this method.
