摘　　要：本文初次提出缓倾顺层岩石边坡的失稳与冰胀作用有一定的成生联系,其层间所夹的泥层与冰胀作用有关;当边坡前沿形成临空面,有层间次生泥层的作用,若不及时支撑防护,边坡的滑移垮塌难于避免;关于冰胀产生的次生泥层,盼能引起工程地质界的关注。In this paper, it＇s the first time to point out the instability of flat - bed planefault rock side slope has some productive relation with ice expansion, the Mud layer of its interlayer is related to the ice expansion. When it forms the free face in the front of side slope and there is secondary shaly formation, it＇s hard to avoid the slid and collapse if not hold in time. About the secondary Mud layer caused by ice expansion, it＇s hoped to draw the attention of the engineering geologists.
