PROBLEM TO BE SOLVED: To provide a method for accurately estimating a load stress of a support for an aerial facility through simple procedures.;SOLUTION: A load stress estimation method includes the steps of: measuring a surface shape of a support, using a three-dimensional shape measuring device of a range finding type from at least two measuring points which are separated from the support for an aerial facility at an azimuth angle 50° or more around the support and included within a range where a distance to the support is 0.2 times or more and 60 times or less as much as a height of the support; calculating a measurement centerline connecting a central position of a horizontal cross section of the support along a height direction of the support and a reference centerline extending perpendicularly through a center at a ground edge position of the support from the measured shape information of the support; calculating a horizontal displacement value at each height position of the support by comparing the measurement centerline with the reference centerline; and using the displacement value to refer to an analytical curve on the basis of measurement data of an article equal to the support, thereby estimating a load stress of the support as a measurement target.;COPYRIGHT: (C)2012,JPO&INPIT
