Toshio Fujihara1, Kazuhiro Watanabe1 (1.National Institute for Land and Infrastructure Management )

Keywords:Earthwork structures, The surface of the earthwork, Earthwork inspection, Point cloud data

By formulating the road earthwork structure inspection procedure, 5 of the long important soil and the high embankment as a specified earthwork structure
It was shown that the inspection was carried out based on the standard and the proximity visual of the inspection frequency once a year. On a large scale,
While it is considered difficult visually to grasp the overall variation, the method of utilizing point cloud data is an effective measure.
It is considered to be. Therefore, in order to verify the problems in the introduction,
The applicability of the variation of the legal surface was confirmed mainly by the mobile mapping system.
