| 摘 要： | 为了准确评价公路边坡的稳定性,针对影响公路边坡稳定性因素的模糊性和随机性,选择影响公路边坡稳定性的10个主要因素,并分为两个层次．利用模糊数学综合评判方法,采用专家方法和经验公式法赋予影响因素的隶属函数和隶属值,建立公路边坡稳定性分析的二级综合评判模型,得到公路边坡稳定性的预测结果。将该模型应用于工程实际,结果证明了该方法的切实可行性和有效性。但对影响因素的选择还需要进一步完善和标准化。

| Abstract: | In order to accurately appraise the road slope stability, ten major factors that affect the slope stability are chosen and divided into two levels in view of fuzzy and random characteristic. The two-level fuzzy comprehensive assessment model of slope stability is established with the method of fuzzy mathematics comprehensive assessment and membership function and membership grades based on expert method and experiential formula, accordingly the forecast result of the slope stability is obtained. Finally, the engineering example is analyzed. The results show that the correctness and effectiveness of this method in road slope stability. But the major factors need further perfection and standardization. |
