摘要
九家湾断层组是全新世活动断层,其第3条断层北东向延伸通过乌鲁木齐市主城区北京路段。通过分析已有成果并结合新发现,在该断层可能通过乌鲁木齐市主城区北京路段的位置布设浅层反射波地震勘探测线,通过分析时间剖面发现了断层异常点位置,在此基础之上布设人工探井进行验证,分析人工探井联合剖面探测成果发现异常段标志地层存在错动迹象,最终确定出断层的准确位置。研究表明,人工探井联合剖面探测标志地层更为直观可靠,探测精度高,是验证浅层地震勘探异常的技术方法有效补充。
The third fault of Jiujiawan faults is a Holocene active fault crossing Beijing road extending in NE direction in Urumuqi. According to recent research progress, this fault may cross artificial shallow seismic survey line in Beijing road of Urumuqi. Through time profile and artificial wells, we found location of abnormal points with fault displacement and then found exact location of fault. The results showed： artificial well combined with time profile detection method were more reliable with high precision which might be the effective complementation to verify anomaly of shallow seismic exploration.
