摘要

丰台地震台和房山地震台数字化三维形变观测曲线均有年变化,但年变化相反,可能与两台站分别位于八宝山内支、外支断裂带有关,且主要由于内支断裂和外支断裂结构的不同引起,断层的不同结构及力学性质,决定了两个台站三维形变观测资料的变化规律不一致。
Both the Fengtai and Fangshan seismic stations are located on the Babaoshan fault in the southwest of Beijing,the two stations three-dirnensional deformation observation curves have annual change,but their annual change law are opposite with each other.The results show that;the above mentioned change of the curves,may be associated with the fact that two stations are respectively located on the internal and external branch of Babaoshan fault, for the internal branch is reverse fault,while the external branch is normal fault,so the phenomenon may be caused by the different nature of the internal and external branch of the fault.
