摘要
建立尖点突变理论模型,对岩质边坡进行研究,考察地下水对边坡软弱介质的影响,并分析滑坡的形成机制以及边坡系统发生突变失稳的必要条件,即介质岩体的刚度比下降是边坡快速失稳的重要因素.结果表明,临界滑动稳定系数Kc <1的边坡并不一定会发生失稳,而Kc>1的边坡有可能蠕滑失稳.验证尖点突变理论在边坡分析中的应用,可为边坡稳定性分析提供参考.
This paper studied ＂the rock slope ＂through establishin groundwater on slope weak medium is great considered to ana g the cusp catastrophe model. The impact of lyze the formation mechanism of landslides he results showed that the main reason of quick instability for slope is declined stiffness ratio. Compared with limit equilibrium stability method and combine the examples analysis showed.- Slope instability would not be necessarily occurred if Kc 〈 1 and creep instability for slope may be occured if Kc 〉 1. This paper verified the correctness of the cusp catastrophe theory on slope analysis and provided an important reference for analysis on slope stability in the future.
