THREE-DIMENSIONAL MEASUREMENT SYSTEM FOR EXCAVATED EARTH RETAINING WORK

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional measurement system for excavated earth retaining works, which grasps the behavior of the whole structure by using a method of measurement of displacement of an earth retaining wall, enabling the behavior of the excavated earth retaining works to be evaluated from a viewpoint of a surface, and which facilitates the grasp of the cause of the displacement.;SOLUTION: This three-dimensional measurement system for the excavated earth retaining works includes: a plurality of sensitive sensors 11-16 which are arranged on the surface of the earth retaining wall 10; a plurality of low-sensitivity sensors 21-80 which are arranged in such a manner as to complement sections among the plurality of sensitive sensors 11-16; a data processor A which performs processing of measurement data from the sensitive sensors 11-16 and the low-sensitivity sensors 21-80; and a display device B which is connected to the data processor A. The three-dimensional measurement system measures the displacement data of the whole surface of the earth retaining wall 10, and grasps the behavior of the earth retaining wall 10 from the viewpoint of the surface.;COPYRIGHT: (C)2011,JPO&INPIT
