摘要:
边坡稳定性受诸多随机、模糊和不完整因素影响,其评价是一个复杂系统不确定性问题。云模型则是处理随机不确定性问题的有效工具,但传统云模型应用于实际边坡评价时,可能面临指标分布形式不符正态分布的要求,为克服此缺陷,在此基于联系数理论和云模型耦合方法,探讨了边坡稳定性非对称联系云评价模型,即基于边坡分类标准求解非对称联系云数字特征和生成联系云,结合指标权重和实测指标计算综合确定度,以判定边坡的稳定性等级。实例应用和与其他方法对比分析表明,该模型应用于边坡稳定性评价是有效可行的,取得了较好效果,且评价结果的转化态势能用确定度统一定量描述,更加符合边坡情况,为边坡稳定性评价提供了新的参考。
Abstract:
The evaluation of slope stability is a complex system uncertainty problem because it involves various random, fuzzy and incomplete factors.Cloud model is a powerful tool to deal with the stochastic uncertainty problem; however, it may encounter such problem that the distribution of some indicators cannot meet the normal distribution requirement.To overcome this defect,herein, an asymmetric connection cloud model for the slope stability evaluation based on connection numbers theory and cloud model was presented.In the model, according to the slope classification standard, the digital characteristics were simulated to generate asymmetric connection cloud.And combined with index weights and the measured indicators, the comprehensive certainty degree was calculated to determine the slope stability grade.The results of the case study and comparison with other methods showed that the model used to evaluate the slope stability is feasible and effective, and can obtain reasonable classification that is more consistent with the slope condition.Moreover, it can quantitatively describe the transformation trend of classification by the certainty degree, and provides a new reference for the slope stability evaluation.
