八宝山断裂带上布设有7处形变跨断层台点,多年来,这些台点形变资料所显示的断层活动性质差异很大,有的互相矛盾。近几年又出现了大的量级变化,是构造活动的加强还是局部环境因素的干扰,众说不一。已有的研究结果认为是干扰所致。通过进一步的实地考察,将多台点资料与地质调查结果进行综合分析,认为八宝山断裂带上观测到的形变变化的主要部分属断层构造活动所致,并非局部干扰所致。不同台点异常变化的不一致性是局部地质构造复杂程度的体现,总体上反映了NW向永定河断裂和NE向八宝山断裂交互分隔的控制作用,并且目前这种作用还比较强烈。这一研究结果对该区域现今地质构造活动的研究以及地展形变的前兆分析都有十分重要的参考价值。
Over the years, there have been seven deformation cross-fault stations on Babaoshan fault belt. The deformation characteristics of these faults show great differences in the nature of faults, and some contradict each other. In recent years there has been a large magnitude change, is the strengthening of tectonic activities or the interference of local environmental factors, different opinions. The results of the research have been considered as interference. Through further field investigation, a comprehensive analysis of multi-point data and geological survey results shows that the major part of the deformation observed in the Babaoshan fault zone is caused by fault tectonic activity rather than local interference. The inconsistency of anomalous changes at different stations is a manifestation of the complexity of local geological structures, and generally reflects the control effect of NW-directed Yongdinghe fault and the interaction between NE and Babaoshan fault. At present, this effect is still relatively strong. The results of this study have very important reference value for the research on the present tectonic activity in the region and the precursor analysis of the deformation of the land expo.
