摘　　要：以马钢“十一五”新区项目马三峰边坡为例,对含软弱夹层的岩石边坡的控稳机制和稳定性进行了分析.结果表明,对顺层岩石边坡,其稳定性决定于软弱夹层的力学强度.软弱夹层强度参数可通过现场剪切试验获得,根据试验所得强度参数,计算得该边坡安全系数小于规范规定的一级边坡安全系数值,需进行加固处理.This paper gives an analysis of the control mechanism and the stability for the rock slope including soft strata by taking as an example the slope of Masanfeng in the eleventh five-year plan of the new area of Magang. The results indicate that the stability of the rock bedded slope is decided by the mechanics strength of the soft strata and the strength parameters of the soft strata can be obtained by the local shearing experiment. The safety coefficient is less than the value regulated by the national norm. So the slope must be reinforced.
