对岩板顺层倾斜边坡和直立边坡变形弯曲的演化过程进行了研究.发现岩板顺层斜坡和直坡在其演化过程中有随机共振和混沌现象.当随机共振发生时，即使较小的随机因素也可引起坡体较大的变形弯曲.随机混沌是由于环境因素的周期性变化，特别是每天和每年的周期性变化所致，混沌的出现使得对滑坡的预测和预报变得较为困难.The paper studies the evolution of the consequent rock block slope (inclined and vertical).We find that there exist stochastic resonance and chaos in the process of evolution.When stochastic resonance happens,any weaker stochastic factors can cause large deformation and crook for the slope.The stochastic chaos is induced by the periodical change of the environment,so the forecast of landslide is more difficult to make.
