Abstract

Abstract:

Active fault is one of potential geohazards in cities. Locating and dating buried active faults in urban areas have been a difficult issue in active fault exploration. In this paper, we take the detection of the buried active fault performed at Hehuan Road in the north of Suqian city as an example. We preliminarily mapped the fault through field investigation and shallow seismic reflection survey technique. Furthermore, based on the principle of doubling section method, we conducted multiple drilling to constrain the upper faulted point which is located in a range of 5m in horizon and 4.4~6.1m in depth. Finally, we determined the exact location and latest activity of the fault by trenching. Obviously, good results have been acquired on the accurate location and activity of the Suqian segment of Anqiu-Juxian Fault using multi-level and multi-means detection method. Besides, we observed from the detection at the Hehuan Road site that at least four paleoseismic events occurred during the past 80000 yrs, and the result indicates that the latest faulting event on the fault is younger than(5.9±0.3)ka BP and the buried active fault at the Hehuan Road is a Holocene active fault. The result of buried active fault detection at the Hehuan Road site provides quantitative parameters for evaluation of seismic hazards and planning the width of safety distance in Suqian City.

Key words: buried fault, location and activity of fault, multi-method detection, Suqian City

摘要：

城市活动断层是城市潜在危害之一, 而对城市隐伏活动断层的准确定位及其最新活动时代的判定, 一直是活动断层探测的难题。文中以宿迁市合欢路隐伏活动断层探测为例, 通过地质地貌调查和浅层地震勘探初步确定断层位置。依据对折定位法原理, 实施钻孔联合剖面探测, 把断层上断点限定在平面5m、深度4.4~6.1m的范围内。再通过开挖探槽, 精确查明断层近地表位置以及断层最新一次活动时间。利用多层次, 多手段综合探测方法, 在合欢路场地对安丘-莒县断裂宿迁段的断层精定位和活动性研究中取得了很好的效果。合欢路场地探测结果显示, 断层最新一次事件发生在(5.9±0.3)ka BP以后, 属于全新世活动断层。
