Abstract: Based upen examples, a basic hypothesis is adv-anced about the accommodation of rock masses tothe weak surfaces and utilization of these surfacesduring the rock failure. It is pointed out that thefailure path in jointed rock masses made of one ki-nd of rock material is roughly similar to that inan integral rock mass made of some equivalent ho-mogeneous material. In addition, the paper points out that a steeprise of the plot of slope displacement versus time isinsufficient for predicting slide. One of the most sp-ectacular examples is the displacemant observationplot of target No. 3 on slope face(w200)at Fushunopenpit coal mine. This paper makes a brief discu-ssion on some problems involving the steep rise ofthe plot tail.
