应用高精度GPS系统对四川丹巴哑喀则滑坡进行监测及稳定性分析
HIGHLY PRECISE GPS MONITORING DEVICES FOR STABILITY ANALYSIS OF YAKAZE LANDSLIDE, DANBA, SICHUAN-BASED ON
摘要
Abstract
Yakaze landslide is a large unconsolidated soil slope, located in Danba County, Sichuan. The landslide has serious deformation and its possible instability can cause serious disaster consequences. The highly precise GPS monitoring is selected for the landslide. This paper explains the application of GPS monitoring to the selection of landslide points, and data processing methods. Over a long series of GPS monitoring from 2007,it is concluded that this landslide has deformed seriously. The total shift rate of the points on the main body of landslide is 0. 6 ～ 0. 9m per year. On the other hand, site survey results show the surface fissures and sere vegetation at the same time, which Indicates that the landslide deformation is serious. The GPS monitoring result is combined with the surface features(i. e. ,the surface fissure and the sere vegetation). It is found that rainfall and the river erosion and scour of the Daduhe river determine the activity of the landslide, the serious deformation of the landslide and the serious geologic hazards. Preventive measures are proposed as well. It is suggested to strengthen the monitoring and early warning forecast work. This paper also points out that during the monitoring period, the effects of Wenchuan Earthquake on May 12, 2008 and human engineering activities were monitored on the impact of landslide.关键词
