摘要
变形是指变形体在各种影响因素的作用下,其形状、大小及位置在时空域中的变化。自然界存在各种形式的变形,如地壳形变、滑坡、采矿塌陷、岩崩、地表沉陷等。与常规的大地形变监测手段相比,GPS定位技术具有测站间无需保持通视,可全天候同时测定点的三维坐标,精度高,速度快,费用少,人力省,作业强度低等优点。在板块运动、地表沉降、陆海垂直监测、滑坡监测等方面,由于GPS高程分量精度得到不断提高,国内外进行了一些科学研究,获得了令人满意的结果和精度。
The deformation is that the deformable body in the role of various factors, its shape, size and location are changed in time and space domain. There are forms of distortion in the nature, such as crustal deformation, landslides, mining subsidence, rock fall, surface subsidence and so on. Comparing with conventional means of geodetic deformation monitoring, GPS positioning technology has the advantage of no need to maintain communication between stations, simultaneously determination the three-dimensional coordinates of points all-weather, high precision, fast speed, less cost, saving man power, and low intensity operations. Since GPS accuracy is increasing elevation component in plate tectonics, surface subsidence, land and sea vertical movement monitoring, landslide monitoring etc., they carried out some researches at home and abroad, and obtained satisfactory results and accuracy.
