摘　　要：张石高速公路涞源段路线通过一古滑坡前缘,路面的开挖会导致滑坡的复活。通过现场调查确定为土—石二元结构面滑坡,采用浅层地震的方法对分界面其进行了勘察,在此基础上对滑坡进行了稳定性评价,针对此类滑坡,本文对治理方案进行了讨论论证,最终提出了以抗滑桩为主,其他方式为辅的综合采用综合治理的措施。此分析方法和治理思路可为类似的工程提供有益的借鉴。The LAIYUAN section of ZHANG-SHI expressway is designed to pass the front of an ancient landslide which will be excavated. It will lead to the reactivation of the landslide. The landslide is investigated by the reconnaissance and shallow seismic exploration methods. Then the landslide stability analysis is studied. The result of analysis is that the landslide must be controlled. On the basis of above study, the synthetic methods of both anti-slide pile and other measurement are put forward in the paper and it provides the reference for the other similar engineering..
