Abstract: The steel bars,Soil nails inserted in natural slope can increase the stability of slope.The nailing-earth system considered as an entirety will support the stability of slope.The reinforced slope is significantly different from the tied back wall.This paper describes the outline of mechanism of reinfored slope,and proposes a modified Fellenius method to the stability analyses of reinforced slope.

Key words: stability of slope, reinforced slope, soil nailling

摘要： 在原位边坡中埋入"锚钉"可提高边坡的稳定性。锚钉边坡可将"钉——土"视为一个统一的整体,由此而形成的"钉——土系统"将共同维持边坡稳定,这是锚钉边坡与传统的锚杆挡土墙的重要区别。本文简明扼要地阐述了锚钉边坡的机理,提出了锚钉边坡稳定分析的修正条分法。
