摘要 为探索GPS在三峡库区滑坡监测中的应用 ,项目组于 1999年 2~ 7月在库区 12个滑坡体上 ,开展GPS观测时最佳时段、最佳时段长度、最佳截止高度角、最佳基准点数及分布 ,选用星历、解算软件、快速静态定位 ,GPS与GLONASS组合定位 ,不同气象参数等项试验与研究 ,获得一批有益的结论。实践证明 ,今后在三峡库区滑坡监测时 ,完全可用GPS代替常规的外观测量方法 ,且在精度、监测速度、时效性、效益等方面都有明显的优势。 To explore the GPS application in the landslides monitoring in the THree Gorges Reservoir Region,12 landslides area inh the region were investigated from Feb.~July,1999.A series of researches and experiments were conducted on many factors,such as best observation time interval,best observation time interval length,best cut off angles,best datum point and layout,selection of ephemeris,solution software,rapid static positioning,composite positioning with GPS/GLONASS and varions meteorological parameters,etc.By analyzing hte investigation results,it was proved that GPS could be applied to substitute the traditional field monitoring in the future for landslide monitoring in the Three Gorges Reservoir region.The GPS method is better than the traditional one in the aspects of precision,speed,efficiency and benefit.
