摘要： 通过几个工程实例，介绍了采用预应力锚索抗滑桩整治公路深层滑坡灾害这一新方法的基本原理、设计方法和整治效果．将锚索的一端锚固于稳定基岩内，另一端与抗滑桩顶相连，然后对锚索施加预应力，将抗滑桩由一端嵌固、另一端自由的“悬臂式”受力状态改变成一端嵌固、另一端支承的“简支”受力状态，从而达到整治滑坡灾害的 目的．近年来，作者采用这种方法整治了30余个滑坡灾害工程，都取得了十分显著的效果．一般可节省灾害整治费用20％一4O％．

Abstract: On the base of several cases，the basic principle、the design method and the effeets of remedy for deep-strata landslide disaster are introduced in this paper by stabilizing piles with prestressed anchor ropes．one end of the anchor rope is embedded in stable rock mass．while the other is connected to the hcad of thc stabilizing pile，and then the anchor rope is prestressed．The stabilizing pile，one end of which is fixed and the ohter is free，is changed from one state of free head into another statee of elastica1ly fixed head，so that the landslide disaster is remedied．In recent years，the author has used this method for remding more than thirty landslides，and all of those have received very well signifieant effects．This method can generally saved a cost of 20％ 一40％ for the deep-strata landslide of highway．

Key words: prestressed anchor rope；stabilizing pile；highway, deep-strata landshde；disaster remedy
