GPS在大坝和滑坡安全监测中应用的研究

Study on the application of GPS to the safety monitoring on dam and landslide

为了在大坝及滑坡安全监测系统中应用GPS技术 ,在武汉大学测绘学院进行了GPS用于大坝、滑波安全监测的可行性试验。在此可行性论证基础上 ,通过隔河岩大坝外观变形GPS自动化监测系统、三峡库区滑坡GPS监测试验 (静态 )和龙羊峡水库近岸滑坡GPS监测 (快速静态 )的实例 ,论述了GPS定位技术完全可以代替常规的监测方法 ,用于各种高精度变形监测领域 ,并且GPS监测系统可以使监测工作实现完全自动化 ,使监测、监控、决策实现远距离控制 ,建立无人值守的监测系统。

To apply GPS technology to dam and landslide safety monitoring,the feasibility tests on the application of GPS to dam and landslide safety monitoring was made in the School of Surveying and Mapping, Wuhan University. On the basis of this feasibility demonstration and through the examples of the automatic surveying GPS system for monitoring the deformation of the Geheyan Dam, the GPS monitoring test (static) on the landslide in the reservoir area of the Three Gorges Project and the GPS monitoring on the bank landslide of the Longyang Gorge Reservoir (rapid static), this paper describes the GPS technology could be used for the landslide monitoring to replace the routine methods. Moreover,the GPS monitoring system also supports the automatic monitoring and enables remote monitoring, remote control and decision reality so that an unattended monitoring system can be set up.
