摘　　要：应用GPS取代传统的地表变形监测网可以提高外业观测的效率，而GPS观测值是三维基线向量，平差结果是地心坐标系的三维坐标。通过多次重复观测数据的动态平差，可获得各监测站的三维移动、三维移动速率，并可求出加速率。本文研究了三维监测网的分期动态平差方位、平差基准的选取和平差成果的利用。It can improve the efficiency to use GPS to replace the traditional method in ground deforming monitoring, but the measurements of GPS are baseline vectors in three dimensions (3-D), and the adjusted results in geocentric coordinate system. The values of movement, moving rate and acceleration in 3-D from the monitoring stations can be obtained by means of the data dynamic adjustment based on the multi-repeated observation. The adjustment method by stages, the method selecting to adjustment datum and the application for adjusted results in 3-D monitoring network are discussed in the paper.
