摘要
本文首先利用拟稳平差方法，并结合测区地质断层分布情况，得出一个变形分析模型。然后根据三期变形观测资料，进行位移与应变分析。经初步分析得出：菲尔德斯海峡断层活动比较显著，在垂直方向上分离后又会聚，其幅度约达17毫米，但总的趋势是分离，其年扩张率约为5毫米。

In this paper, a model for deformation analysis is set up by using the method of quasi-stable adjustment in combination with the distribution of faults in the monitored area. Then displacement and strain analyses are performed using the data from observa tions made in three epoches: preliminary analysis indicates that Fildes strait exhibits p-ronouned faulting activities, vertical displacement is characterized by converging after separating with moving range of about 17mm. However, the general trend is separation, the spreading rate is about 5mm per year.
