Analysis and Prediction on Instability of Bedding Slope

关于边坡失稳的预测预报,已有半个多世纪的研究进程,到目前为止仍处于探索阶段。边坡的失稳演化过程中与其内部结构和外界因素的影响密切相关。通过对摩擦定律的状态分析,研究了边坡失稳的内在机制,并论证了边坡失稳预测的充要条件,探讨了中长期预测预报失效的原因。

The prediction of slope instability has been studied for more than half a century,but it is still in the stage of exploration. The failure evolution relates to the internal structure and external factors closely. In the paper,by state analysis from the law of friction,the intrinsic mechanism of slope failure was studied,and then taking the necessary and sufficient condition for the prediction thereof as the argument,the reasons why the medium- or long-term prediction are invalid were discussed.
