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 evolution of deformation and bending of beveled slopes and upright slopes in rock slabs was studied. It is found that the slopes and straight slopes of rock slabs have stochastic resonance and chaos during their evolution. When stochastic resonance occurs, even small random factors can cause large deformation and bending of the slope. Random chaos is caused by the cyclical changes of environmental factors, especially the daily and annual cyclical changes. The appearance of chaos makes it more difficult to predict and predict landslides.
