| The measurement of displacement is one of the most important measuring items for safety management of concrete gravity dams. It is usually done with plumb lines. This displacement measurement method is highly accurate; however is cost-consuming, and the settings up works have a large effect on the dam construction worksThe Public Works Research Institute has made enthusiastic research on effective utilization of GPS to measure displacement of embankment dams, which have generally larger displacement compared to concrete gravity dams. If we can confirm the applicability of this measurement system to concrete gravity dams, there is the possibility to make the displacement measurement for concrete gravity dams more sophisticated and inexpensive. In this study, we introduced the displacement measurement system with GPS to a concrete gravity dam, and examined its applicability. |
