´˜^i‰pjF |
This paper studies the application of the RTK-GPS to real-time measurement of large ground deformation during a large earthquake. The RTK-GPS can measure relative movement of one receiver with higher accuracy than a single receiver. In a large-scaled ground deformation experiment carried by PARIS, the following three were examined: 1) the robustness; 2) the accuracy at static state; and 3) the accuracy at dynamic state. The accuracy of dynamic and static state is compared with the automatic-laser-traced total station measurement and the image analysis of video records, respectively. Major findings are 1) the robustness is at an acceptable level; 2) the static state accuracy is around 1[cm], which is enough to monitor the large ground deformation,; and 3) the dynamic state accuracy is good to measure slow but large deformation
