METHOD TO DETECT DEFORMATION CHARACTERISTICS OF STRUCTURES Russian patent published in 2011 - IPC G01M99/00 

FIELD: construction.

SUBSTANCE: method consists in marking of controlled points along the specified sections of the structure and cycle-by-cycle detections of their position. At the same time controlled points are linked to geodesic horizontal and vertical points, then analysis of measurement information is carried out. At the same time previously a multi-tier horizontal and vertical geodesic base is formed, both outside the structure and inside it in a single coordinate system, at the same time this coordinate system is matched with the structure coordinate system, then the detected points are marked. Monitoring of external geometric parameters of the structure is carried out in stages, at the same time monitoring of position of points arranged on vertical building structures is carried out by the method of spatial polar cross-bearing, position of controlled points arranged on horizontal building elements is detected by the method of geometric levelling, at the same time positions of detected points arranged in a moment area are detected ten times more accurately than positions of detected points arranged in a momentless area, positions of detected points arranged in a transition zone are detected five times more accurately than positions of detected points arranged in a momentless area, internal geometric parameters of the structure are detected before and after performance of all stages of external geometric parameters detection.

EFFECT: detection of complete and valid information on deformation characteristics of a test subject.
