中文摘要：
由于边坡问题的复杂性,有必要对边坡的安全稳定进行综合评价。在边坡的综合评价中,评价体系的建立和评价因素权重的确定十分重要。为充分考虑边坡的现场情况,基于长期的监测资料,建立边坡安全稳定的综合评价体系。针对评价因素权重确定中的困难,把突变理论运用到边坡的综合评价中,利用突变理论在多准则评价决策中的优点,避免人为确定权重的主观性。具体实施步骤是首先对多层评价目标进行分解,在将底层评价指标进行标准量化后,运用不同突变模型的归一公式进行计算,从而计算出边坡安全总突变级数值,实现对边坡安全的综合评判。通过工程实例的计算表明,该评价方法是合理、可行的,为边坡稳定的综合评价提供新的思路。
英文摘要：
Due to the complexity of slope project,the comprehensive assessment is necessary to the slope safety and stability.In the comprehensive assessment,the establishment of assessment system and the determination of weight are both very important and difficult.In order to consider the field situation of slope,the comprehensive assessment is established based on the long-time monitoring data.Aiming at the difficulty of defining weight value,the catastrophe theory is used in the comprehensive assessment,and the specialty of catastrophe theory in the multi-rule assessment is utilized to avoid the subjectivity of artificial weight.The concrete steps of practice is to analyze the multi-layer assessment object first.After standard quantizing of bottom assessment index,the ultimate catastrophe function is obtained through quantitative computing by the normalization formula of different catastrophe models,and thus the comprehensive assessment of slope safety is realized.The engineering example indicates that the new assessment method is reasonable and feasible,and it provides a new idea for slope assessment.
