From the principles of modern soil mechanics, the structural and swelling characteristics of soft clayey rocks were analyzed systematically.
结合现代土力学原理，系统分析了风化泥质软岩的结构特征，膨胀特性；
The deformation and failure under coupled action is more serious than the other situations, and softening action is more disadvantaged to the stability of surrounding rocks than swelling.
耦合作用下，围岩的变形和破碎比单因素作用下更加严重；其中线性软化对巷道稳定性的影响比破裂膨胀更大。
