【摘要】 在全面收集和总结前人工作资料的基础上，采用野外地震地质学研究方法，结合浅层地震勘探、断层气测量、开挖探槽、年代测样等丰富的第一手资料，综合分析总结了青海省格尔木市温泉水库近场区内活动断裂的特征及其古地震形变遗迹。特别是对穿越坝体的京昆仑活动断裂进行了更为详细的研究，总结出它是全新世以来经过多期强烈活动，水平位移达40～80m，平滑速率为7．5～9．5mm／a，是古地震遗迹十分状观的一条岩石围深大断裂。更多还原

【Abstract】 Based on the gathered and summarized data,the authors use the methods of seismogeology survey,shallow earthquake exploration,radon measurement,trench research and chronostratic determination,analyse comprehensively the characteristics of active fractures near Wenquan reservior in Ge’ermu city,Qinghai province,and paleoearthquake deformation traces.They especially study east Kunlun active fracture across the reservoir dam,which is a deep lithospheric fracture zone whose horizontal displacement is 40~80m,smoothing rate of speed is 7.5~9.5mm/a with many grand paleoearthquake traces.更多还原
