Study on the reference datum stability evaluation methods of land subsidence leveling network
摘要
Abstract
Reasonable selection of regional land subsidence monitoring network reference datum, wil directly affect the accuracy and reliability of the subsidence monitoring information. Since selection of different reference datum, the settlement of information wil vary. This paper uses the free network adjustment algorithm to calculate the leveling network correction and adjustment of elevation values, and then using the mean spacing method and the single point inspection to evaluate the stability of the reference datum, then determine the deformation model. Final y combining the example of the method are veriifed, formed a set of suitable for engineering application of reference datum stability analysis method and process.关键词
