| 摘 要： | 吉林延边地区广泛发育着的膨胀性软岩使得在开挖公路边坡过程中发生了数例滑坡。文章通过珲春组和龙井组膨胀性软岩两个典型滑坡的反演抗剪强度指标，采用MSARMA法对两种地质条件下不同开挖高度及坡度边坡进行稳态分析，获得边坡临界几何参数，并进行回归分析，获得该地区开挖坡高和坡角的相关关系。

| Abstract: | The expansive softrock extensively developed in Yanbian region initiated several failures of slope. The shearing strength index of typical case histories were analyzed via back analysis. Employing MSARMA method, stability analysis with regard to varying height were performed and the correlationship between height and critical inclination of slope in relation to different geologic condition were eatablished. |
