应用GPS定位技术监测滑坡体垂直形变研究

THE STUDY OF USING GPS TECHNOLOGY TO MONITOR THE SLOPE VERTICAL DEFORMATION

在研究了几种常用的高程系统及其相互关系的基础上 ,从理论上论证了GPS所测得的大地高HGPS的变化同样可以反映滑坡体的垂直运动 ,并结合有关的实验研究了GPS大地高在滑坡监测中的精度及实际应用的效果 ,从而得出了GPS定位技术可用于监测滑坡体垂直运动的结论。

Based on the research of several height system usually used and their relationship, it is proved in theory that the slope vertical deformation is also reflected by the value of the geodetic height's differences obtained from GPS. With some correlative experiments, this paper researches the precision of GPS geodetic height and the effects in practice in monitoring the slope vertical deformation. Then the conclusion is obtained that the GPS technology can be used in monitoring the slope vertical deformation completely.
