（中铁二院西北勘察设计有限责任公司，兰州 730000）[摘要] 2010年4月14日玉树地震诱发了约2036处滑坡。根据对玉树地震滑坡特征的调查，玉树地震滑坡具有受地表破裂控制作用强烈、滑坡密集成片分布、滑坡以崩塌堆积型滑坡为主的特征。分析了了滑坡受工程活动、地表水下渗、地震震动影响行车滑坡的机理，并提出了以锚索、抗滑桩为主的工程整治措施。[关键词] 玉树地震; 滑坡; 特征; 形成机理; 治理措施中图分类号：U412.22+2 文献标识码：A 文章编号：1002-848X(2013)S2-0686-04作者简介：金增芳，学士，工程师，Email: lz96zcj@163.com。Yushu seismic landslide characteristics, formation mechanism and control measuresJin Zengfang(CREEC (Northwest) Survey and Desig Co., Ltd., Lanzhou 730000, China)Abstract: Yushu earthquake happened on April 14, 2010 and it triggered about 2036 landslides. According to .investigation of the landslide characteristics caused by the Yushu earthquake, Yushu earthquake landslide has characteristics as following strong control action of surface rupture, intensive piece distribution ,and mainly collapse accumulation landslide. Analysis of the landslide by engineering activities, surface water infiltration, seismic vibrations affect driving landslide mechanism-based cable, anti-slide pile engineering remediation measures.Keywords: Yushu seismic characteristic; landslide; characteristics; formation mechanism; control measure
