摘　　要：基于区域地质、地震地质及地质灾害方面的资料,并结合详细的野外调查,采用定性、半定量的评估方法,对北京轨道交通昌平线(S2线)工程建设用地地质灾害危险性进行预测;工程项目可能引发或加剧及可能遭受的地质灾害类型主要有地面沉降、砂土液化、活动断裂、基坑边坡失稳、底板突水和桥梁地基失稳等,针对评估结果提出地质灾害防治对策,以期为该项目防灾减灾、应急救援及类似工程地质灾害危险性评估提供参考。Based on regional geology, earthquake geology and geological hazards information, combined with detailed field investigation, the risks of geological hazards of Changping electric transport line （S2 line） are evaluated by qualitative, semi-quantitative methods, it shows that there would be six sorts of geological hazards caused or intensified or suffered in the process of the construction project, including, ground subsidence, soil liquefaction, active faults, foundation slope instability, water inrush and bridges foundation instability. According to the results of the evaluation, prevention and control countermeasures against geological hazards are put forth so as to provide references for geological hazards prevention and mitigation, emergency rescue and similar engineering geological hazards evaluation.
