摘要
鲜水河断裂带是我国西部一条重要的活动断裂带,总体上由8条分支断裂组成,全新世以来以左旋走滑为主,地震活动频繁,炉霍断裂是该断裂带内的一条重要分支断裂。本文在资料收集分析、遥感解译、野外调查、槽探、物探和地质测年的基础上,补充厘定分析了炉霍断裂的空间产状和晚第四纪以来的活动性。认为该段断裂总体走向为NW320°~340°,断面以倾向SW为主,倾角一般为70°~80°,局部近直立,以左旋走滑为主。沿炉霍断裂,一系列水系、冲沟发生左旋位错,炉霍县城西北萨其卡沟晚更新世以来最大水平位错为2100m、陡日沟的最大错距为1800m,结合TL测年数据,得到该段断裂晚更新世以来的平均滑动速率为(10.58±1.16)~(11.09±1.22)mm/a;尤斯村段现今地表破裂清晰,槽探剖面揭示7次古地震事件,强震平均复发周期为230~330a,地震活动频繁,在将来一段时间内发生强震的危险性高。该研究对于铁路规划选线和地方防灾减灾工作具有重要的指导意义。
The Xianshuihe fault zone is an important active fault in the west of China,which is composed of eight branch faults on the whole,characterized with sinistral strike-slip,high earthquake activity frequency since the Holocene,and the Luhuo fault is an important branch of the Xianshuihe fault zone.Based on the data collection and analysis,remote sensing,field investigation,trenching,geophysical test and geological dating,this paper made complementary analysis on the space occurrence and activity of Luhuo fault since late Quaternary.This paper argues that the general trend of the fracture is NW320°~340°,the cross section is given priority to the tendency of SW,main dip angle is 70°to 80°,commonly local nearly up-right,predominantly sinisterly strike-slip.Along the Luhuo fault,a series of drainages and gullies were dislocated with left-lateral characteristics,the maximum horizontal dislocation of Saqika gully in the northwest of Luhuo County is about 2100 m,and the most dislocation of Douri gully is 1800 m since late Pleistocene,with the TL dating data,we can conclude that the fault slid with an average rate of(10.58 ±1.16)mm/a~(11.09±1.22)mm/a since late Pleistocene.The surface rupture in Yousi village is clear according to the geology survey,and the trench profile reveals 7 ancient seismic events,with the strong earthquakes average recurrence period of230 ~ 330 years,and earthquake activity is frequent,earthquake risk is high in the near future,since the last strong earthquake in 1923.The study has great important guiding significance for railway line selection and local disaster prevention and mitigation work.
