The measurement of exterior deformation is one of the most important measuring items for safety management of embankment dams. We enthusiastically made the research to develop the GPS automatic displacement measurement system for measuring exterior deformation of embankment dams. At present, this system has already been installed at many embankment dams. In this paper, we systematically summarize the results of our previous studies and other researchers’ studies on this topic. In addition, we introduce the outlines of engineering manual on this technology, which we are preparing. |
