喷锚支护作为用于边坡加固的一种常用形式，其加固机理较为复杂，因此如何有效地评价喷锚支护后边坡的稳定性对实际工程非常重要。针对喷锚支护边坡的稳定计算问题，通过力等效原理把锚杆的集中力转化为作用于边坡坡面的面力。结合极限平衡原理将简化后的面力用于边坡的稳定性计算，得到锚固力均化后的边坡稳定计算公式。将提出的方法应用于长河坝导流洞出口喷锚支护边坡的稳定计算，并与传统方法的计算结果进行对比分析。计算结果表明：面力等效法计算得到的边坡抗滑稳定安全系数与传统算法结果差异较小，表明提出的方法用于分析喷锚支护边坡稳定是合理可行的。

Shotcrete-bolt supported measure is a common treatment method for slope reinforcement .Because of the reinforcement mechanism of shotcrete-bolt supported measure for slope is very complicated ,how to effectively evaluate the slope stability after rein‐forcement is very important to actual projects .According to the slope stability analysis of shotcrete-bolt supported slope ,the concen‐tration force of bolts is transformed into uniform force effect on the slope surface by using force equivalence principle .Combing the limit equilibrium method and the equivalent uniform force ,the stability analysis method is presented for the shotcrete-bolt supported slope .Finally ,the presented method is used to evaluate the stability of outlet slope at the Changheba Hydropower Station ,and com‐pared with the traditional force concentration method .The results show that ,the safety factor of slope computed by presented meth‐od is very close to traditional method ,which means the presented method can be used to analyze the stability of shotcrete-bolt sup‐ported slope .
