    青海玉树Ms7.1级地震地质灾害主要特征

    RESEARCH ON MAJOR CHARACTERISTICS OF GEOHAZARDS INDUCED BY THE YUSHU Ms7.1 EARTHQUAKE

    • 摘要: 2010年4月14日7时49分,青海省玉树县发生Ms7.1级地震。玉树地震产生较连续的地表破裂和大量房屋破坏,并诱发了滑坡、崩塌和震裂山体。此外,地震诱发的砂土液化、水渠溃决等加剧了局部山体地质灾害。通过现场调查和地震前后玉树县地质灾害发育状况,简要阐述了地震地质灾害的主要发育特征,包括震后地质灾害数量明显增加、地震地质灾害分布受活动断裂控制、低位滑坡为主、地质灾害链生效应显著等,并对灾后重建过程中的地质灾害防治提出了建议。

       

      Abstract: The Yushu Ms 7.1 earthquake was happened at 7: 49 on April 14, 2010 in Yushu county of Qinghai province. Besides continuous surface rupture and a large number of properties collapse,the types of geohazards induced by earthquake include rock fall,landslide,potential debris flow,etc. In addition,the geohazards can be aggravated by the earthquakeinduced sandy soil liquefaction,as well as burst of a channel,in local areas. Based on field investigation and comparison of the geohazard data before and after the Yushu earthquake,the authors summarize the major characteristics of the Yushu Ms7.1 earthquake,such as the amount of geohazard increasing obviously after the earthquake,the distribution of geohazards controlled by the active faults,the lowposition soil/colluvial landslides predominant,the effect of geohazard chain being notable,etc. some proposals for geohazard control during reconstruction have been given forth in this paper.
