摘　　要：滑坡是一种危害极大的地质灾害 ,它的整治方法研究具有重要意义。抗滑桩是一种适应性强、对滑坡稳定性和地质环境干扰小、工期短、抗滑能力强的滑坡整治方法。风动潜孔锤钻进是一种具有许多优点的钻进方法 ,它的许多特点 ,如成孔质量高、应用范围广、无液体循环介质、钻进规程参数小、可实现大直径基岩钻孔等都适合于抗滑桩施工。文章在介绍风动潜孔锤钻进特点的基础上 ,根据抗滑桩施工要求 ,分析了风动潜孔锤用于抗滑桩施工的可行性 ,并举出了其应用实例。Landslide is a geological hazard with serious losses.It is very important to research the controling methods.Slide-resistant pile,which has many advantages such as high adaptability,little interference to landslide and geological environment,short construction time,high silde resistance,is a main method to control landslide.Pneumatic down-the-hole hammer is a drilling method with many advantages.Its features,such as wide application range,high hole quality,no circulating medium,low operation regulations,and drilling big diameter rock hole,fit to construct slide-resistant pile.According to the requirement of silde-resistant pile construction,this paper analyses feasibility that pneumatic DTH hammer drilling applies to construct slide-resistant pile on the basis of introducing the features of pneumatic DTH hammer.Then an applied example is given.
