全站仪相对变形测量方法

eformation monitoring results to get the change of deformation of the body relative to its initial state, for small-scale monitoring of the displacement calculation can not depend on the unified surface, that is has nothing to do with the reference ellipsoid and the geoid, and thereforemeasurement of many factors unrelated to, such as the deflection of the vertical curvature of the Earth, the accuracy of the reference point, but only with a few necessary observations, thus making the deformation monitoring is simple and efficient, and high-precision monitoring results. This method is suitable for periodic deformation monitoring in the fixed reference point on the deformable body, and the plane displacement monitoring can use any two-dimensional Cartesian coordinate system, the vertical displacement monitoring can be horizontal as the datum.
