The paper concludes the research of slope engineering and landslide forecast . in the base , nonlinear theory and relative theory and methods are used to nonlinear mechanism of slope evolution and the characteristic chaos of slope and landslide prediction and forecast methods
本文总结了边坡工程及滑坡预测预报领域的研究成果，在此基础上，运用非线性理论的相关理论和方法，对边坡演化的非线性机制、边坡的混沌特征、滑坡预测和预报方法进行了较为系统的研究和探讨。
The judgement formula for high and low speed landslide and a new theory of stiffness - effect instability are presented for the instability of planar - sliding slope by the catastrophe theory . it is pointed out that the limit equilibrium stability analysis method of rigidity body has a lot of defects . the relationship between the action of outside environment and the response of slope system is complicatedly nonlinear according to the nonlinear dynamics model of slope evolution built
针对斜坡平面滑动失稳问题，运用突变理论方法，给出了快速滑坡和慢速滑坡发生的判据，验证了刚体极限平衡稳定性评价方法有较大缺陷；根据斜坡演化非线性动力学模型，发现斜坡演化过程会出现混沌现象，其通向混沌之路是通过倍周期分叉实现的。
