The method is different from the one by a single station, and has the characteristics of the displacementparameters and accuracy estimated and tested for all GPS stations.
其特点是能对所有GPS站的位移参数及其精确度进行估计和检验，这与通常的单站变形分析方法不同。

According to the deformation of single cell box girder cross-section, the displacementparameters were designed, and the displacement modes of cross-section distortion angles were deduced.
根据单箱单室箱梁截面的变形，设计位移参数，导出横截面横向、竖向畸变角的变位模式。
