摘要
采用浅层地震技术对北京市立水桥附近的黄庄—高丽营隐伏断裂浅部活动特征进行探测,研究其活动形变特征。结果表明:立水桥附近区域的浅部(150 m以内)地层为3层结构,黄庄—高丽营断裂是由多条断层组合而成的、至今仍在活动的隐伏断裂;断裂上盘存在沉降中心,不同时期沉降中心位置不同、沉降幅度不同;受沉降中心的牵引,沉降带边缘产生了多条小断裂。这些特征为黄庄—高丽营隐伏断裂的整体研究提供了可靠的依据,也为浅部活动性提供了证据。
The shallow deformation through active Huangzhuang-Gaoliying fault near Lishuiqiao in Beijing urban area was investigated with high-resolution seismic exploration.The results indicate that there exists structure of three layers at the shallow part of the area,and the active fault consists of many concealed faults which remain active at present.There are multi-subsidence centers on the hanging wall of the fault which are characterized by different locations and different subsidence ranges in different periods.Lots of small faults were produced beside these subsidence centers.According to these characteristics,the activity of Huangzhuang-Gaoliying Fault can be studied reliably.
