摘　　要：高危边坡存在地质构造不稳定、岩层变化等情况,地质活动会使得其周边的小水电站大坝出现局部受力,发生微小位移和形变,使得监测结果存在较大误差。为此,引入北斗卫星技术,提出高危边坡小水电站大坝形变多点位监测方法。利用北斗卫星技术设计用于大坝形变多点位监测的形变监测系统,结合北斗卫星对大坝形变实时监测,以提供厘米级甚至亚米级的位置信息,有效采集形变数据,获取其变形与位移规律,为日后水电站大坝维修管理提供精准的依据。研究结果表明,利用该方法开展水电站高危边坡大坝形变多点位监测时,监测精度高、效果好。High-risk slopes are characterized by unstable geological structures and changes in rock strata.These geological activities will cause local stress on the dams of small hydropower stations around them,resulting in small displacement and deformation,which will lead to large errors in monitoring results.Therefore,Beidou satellite technology is introduced to propose a multi-point monitoring method for dam deformation of small hydropower stations on high-risk slopes.A deformation monitoring system for multi-point monitoring of dam deformation is designed by using Beidou satellite technology.Combined with real-time monitoring of dam deformation by Beidou satellite,it can provide centimeter-level or even sub-meter-level position information,effectively collect deformation data,obtain its deformation and displacement laws,and provide an accurate basis for dam maintenance and management of hydropower stations in the future.The research results show that this method has high monitoring accuracy and good effect when multi-point monitoring of dam deformation on high-risk slopes of hydropower stations is carried out.
