GPS技术在三峡库区云阳县滑坡监测中的应用
|
摘要
GPS定位技术的快速发展为滑坡监测提供了一种快速高效可靠的方法。利用GPS技术对三峡库区云阳县渠龙村滑坡进行了监测。为跟踪滑坡体随时间变化的动态位移信息,根据最终监测数据绘制的监测点时间序列曲线图,分析了各监测点随时间变化的情况。实践证明:所采用的监测手段和分析方法能快速有效的应用到库区大部分滑坡监测之中。
The rapid development of GPS positioning technique has provided a quick,efficient and reliable way for landslide monitoring.GPS technology was used to monitor the Qulong village landslide of Yunyang area of the Three Gorges Reservoir. In order to track timevarying dynamic displacement of the landslide,the circumstances of the monitoring points were analyzed according to the time-series curves of the monitoring points.The engineering practices prove that the monitoring technique and the analysis method can be applied quickly and effectively to the most of the landslide monitoring of the reservoir.
