摘　　要：我国约有1/3的滑坡灾害发生在黄土地区。黄土滑坡作为发育较为普遍的一种不良地质现象,坡体常常伴随有泥岩、红黏土、古土壤等隔水层或软弱夹层,具有分布广、危害大、隐蔽性强、易多次滑动的特点。在总结前人经验的基础上,对离隰高速某一处典型黄土滑坡进行局部卸载后采用微型钢管桩与挡墙组合支挡的方案进行处治,取得了良好的效果。该方案的成功实施为今后类似工程的治理提供了借鉴。About one third of landslides in China occur in loess areas.As a kind of unfavorable geology,loess landslide is often accompanied by mudstone,red clay,paleosoil and other water-insulating layers or weak interlayers.It has the characteristics of wide distribution,great harm,strong concealment and easy to slip many times.On the basis of concluding past experience,a typical loess landslide in Lishi-Xixian Expressway is treated by the scheme of miniature steel pipe piles and retaining walls after local unloading,which has achieved good results.The implementation of the scheme provides some reference for similar engineering treatment in the future.
