Abstract: The anti-slope structure with nail and anchor is a new and an effective technique dealing with landslides .It is composed of prestressed anchor , nail and concrete grid beam, and it can make incompact soil to be a semi -rigidity mass, so as to increase the mechanics parameter of landslide .The prestressed anchor is anchored in rock, making whole structure to stand against soil press of upside and other load.The authors expound the function mechanism of the new structure in this paper , and take some applications as cases in the paper .It provides reference to similar engineering practices.

Key words: anti-slope structure with nail and anchor, prestressed anchor rope , landslide thrust, safety factor

摘要： 钉锚复合抗滑结构是治理滑坡的一种新型有效的技术.钉锚复合抗滑结构由被加固土体、预应力锚杆(索)、锚钉和砼格构梁组成,锚钉使松散滑坡土成为一个准刚性体.预应力锚杆(索)则将此准刚性滑坡体锚固于稳定基岩中,使整个结构抵抗上部传来的土压力和其他附加荷载.笔者对钉锚复合抗滑结构的作用机理进行了论述,并介绍了在治理滑坡或欠稳定斜坡中的具体应用.
