【Abstract】 By using the basic theory of the free-net adjustment (ranks and defects), three-dimension strain has been analysed according to the horizontal and vertical deformation data. The magnitudes and directions of the main strain are expressed as an ellipsoid. An example refects the strain distributionof of a geodetic quadrilatcral accross the Mengshan fault, Feicounty, Shandong province.更多还原
