Method and apparatus for detecting the deflection, and architectural structures or geotechnical be equipped with such a device

摘要

(57) by detecting the sum of the local deformation over a distance 2m least [Abstract], to detect "long baseline" comprehensive deformation structure (1), an increase of the optical pulse passing through to indicate the degree of elongation by attenuation to be, to use the (8, 11) detection line consisting of a fiber optic preferably. In order to detect the direction and magnitude of deflection occurring structures in (1), matrix following the bending deformation structure (1) and (13), at least one, and preferably detection line two (8, were closely with (1) structure an apparatus including a 11), the difference in elongation change extension and / or change detection line (8, 11) becomes the deflection data device, the structure data is (1) As will also data on deflection, to be placed within the cross section of the matrix (13) of the detection line of the two (8, 11). Use for the purpose of deflection of the structure inaccessible or partially, difficult access, measurement of the warp, and the measurement of subsidence and leveling.
