丹东四道沟跨断层水准观测的数据分析及构造意义

Data Analysis and Tectonic Significance of Crossing Fault Leveling in Dandong Sidaogou

通过对丹东四道沟跨断层水准数据的分析,发现观测数据具有周期变化规律,将其和气温、降水等辅助观测数据进行相关性分析,并利用处理后的数据初步探讨与周边强震的对应关系以及尝试解释断裂构造的性质。结果显示:四道沟所处断裂呈右行走滑运动、顺时针转动。

In this paper, the correlation between periodic variation of Sidaogou cross-fault leveling data and auxiliary observation data such as temperature and precipitation in Dandong are analyzed. Based on the processed data, the corresponding relationship with the surrounding strong earthquakes is discussed, and the properties of fault structures are attempted to explain. The results show that the fault in the Sidaogou is characterized by right-lateral strike-slip.
