GPS与水准测量相结合在景阳滑坡监测中的应用

摘要

为分析GPS与水准测量在滑坡监测中的运用情况,将二者相结合,对湖北恩施清江库区景阳滑坡群进行了监测。通过跟踪滑坡体随时间变化的动态位移信息,并根据最终监测数据分别绘制水平位移和垂直位移的过程曲线,分析了滑坡体各监测点随时间变化规律。实践表明,GPS与水准测量均能反映滑坡的变化情况,且监测结果较为一致,可广泛运用于库区滑坡监测中。在不方便使用常规测量手段的个别滑坡区域,可以只用GPS来进行滑坡监测。%To analyze the application effect of GPS and leveling in landslide monitoring, we monitored the Jingyang Landslide Group in Qingjiang Reservoir area of Enshi, Hubei Province using the two methods. The curves of horizontal and vertical dis-placement with time were obtained on the basis of the final monitoring data through tracking the dynamic displacement information of the sliding body, and the variation laws of the displacement of each monitoring point with time was analyzed. It shows that both the two methods can reflect the variation condition of the landslide and the monitoring results are consistent with each other, which can be applied in the monitoring of landslide in the reservoir area. Individual landslide area where conventional measuring methods are not applicable can be monitored only by the GPS.
