摘　　要：土坡水平加筋是一种使用广泛的加筋方式,但常用的垂直条分法无法有效地分析水平筋材的效果。研究采用Morgenstern-Price水平条分法分析新型加筋土坡的稳定性,根据条块力与力矩平衡,分别推导出安全系数Fs和比例系数λ的表达式,迭代得到计算结果。通过与水平条分简布法和水平瑞典法的算例对比分析,证明方法具有可行性,为边坡工程加筋技术提供理论参考。Horizontal reinforcement of the slopes is one of the most widely used reinforcement methods. In this paper,the stability of the new-type reinforced soil slope is analyzed by morgensternprice horizontal bar division method,and the expressions of safety coefficient Fs and proportionality coefficient divisor are derived respectively according to the balance of bar force and moment,and the calculation results are obtained by iteration. Through the comparison and analysis of the numerical examples of horizontal slitting and horizontal Sweden method,the feasibility of this method is proved, which provides theoretical reference for reinforcement technology of slope engineering.
