METHOD FOR AUTOMATICALLY MONITORING THREE-DIMENSIONAL DISPLACEMENT OF ARCH DAM DEFORMATION

摘要

A method for automatically monitoring the three-dimensional displacement of an arch dam deformation. The method comprises: dividing an arch dam into n segments; measuring a three-dimensional displacement value of an end point of a first segment; and monitoring the three-dimensional variation of an end point of each segment relative to the previous end point, so that three-dimensional displacement values of the end points of all the segments can be obtained according to a transfer principle. The method overcomes the defect that an original measuring method can only monitor a one-dimensional or two-dimensional displacement, and cancels the monitoring of corner parameters of a platform part of a measured point, optimizes a measurement procedure, simplifies a measurement device, improves the reliability of measuring, and reduces the costs of measuring.
