GPS监测山体滑坡方法的研究

采用GPS相对静态定位技术监测山体滑坡,从滑坡监测网的基准点、监测点设计和观测出发,提出了利用高精度全站仪提供的尺度与方位基准来获得相对稳定不变的基准点坐标数据方法;在监测数据处理中对于不同监测周期的网形、起算点选取等对解算结果产生的影响进行了试验研究,提出适宜的解决方法,为今后的山体滑坡GPS监测提供理论和技术依据。

STUDY ON METHOD OF MONITORING LANDSLIDE WITH GPS

By adopting a relatively static positioning technology of GPS to monitor the landslide,this paper puts forward a method of getting relatively stable and unchangeable coordinates data of datum points by using scales and orientation benchmark provided by Total Station with high precision,basing on datum points of landslide monitoring network,the design and observation of monitoring points.It makes an experimental study of the effect on calculating results from different monitoring period's network and choosing known points for calculating and so on,during the period of processing of monitoring data.It puts forward a feasible solution and provides theoretical and technical bases for the future landslide monitoring with GPS.
