【摘要】 美国PBO计划用GPS、体应变等方法研究板缘变形。GPS、体应变、地下水同步观测在东三旗台已有二年半的时间,对该台观测数据的分析结果表明,这种方法不仅能观测到固体潮和地面沉降,还观测到了地壳变形异常。由此可见,对于板内土层GPS连续观测站的研究是GPS领域中的一项重要内容。更多还原

【Abstract】 The PBO plan of American is to study the deformation of plates′ edge by using the methods of GPS,body-strain etc.The station of Dongsanqi has been using the methods of GPS,body-strain,and Underground-water to monitor crustal deformation synchronously for half and two years.By analyzing the data of the station, it indicates that these three methods can not only monitor the solid earth-tide and subside of ground,but also can monitor the crustal deformation.That is why the study of the GPS fiducial station inside plates of soil is an important content of GPS observation.更多还原
