| 摘 要： | 对四川丹巴县甲居滑坡开展的GPS监测表明,甲居滑坡可以分为南北两个区域,其中北部区域滑动较为明显;滑坡体北部水平位移速度53mm/a～200mm/a,垂直位移速度-3 mm/a～-21mm/a;滑坡体南部水平位移速度12mm/a～36mm/a,垂直位移速度-1mm/a～-5mm/a。GPS提供的水平位移量趋势性较好,而垂向位移量结果异常较多,反映出GPS的水平监测优势。GPS监测精度达到毫米级,完全满足滑坡监测的精度要求。

| Abstract: | The GPS monitoring has been conducted on the Jiaju landslide in Danba,Sichuan.The Jiaju landslide may be separated into the northern and southern parts.In the northern part of the landslide,the horizontal displacement velocities range from 53 mm/a to 200 mm/a,and vertical displacement velocities range from-3 mm/a to-21 mm/a.In the southern part of the landslide,the horizontal displacement velocities range from 12 mm/a to 36 mm/a,and vertical displacement velocities range from-1 mm/a to-5 mm/a.By and large,t... |
