| 边坡稳定性分析是不确定性问题,伴有随机性的同时兼具模糊性.本文通过运用主成分分析法优选影响岩质边坡稳定性的特性指标,进而构建边坡稳定性模式和待识别边坡的隶属函数,并确定计算贴近度的方法,以此建立了边坡稳定性的模糊识别模型.在通过模型进行实例仿真的过程中,为综合考虑各种因素对边坡稳定性影响程度的大小,用德尔菲(Delphi)方法确定了各特性指标的权值,使计算结果更趋合理,发现识别结果与与采用传递系数法在天然工况和暴雨工况下计算所取得的结果一致,充分说明利用所建模型对边坡稳定性进行判别具有较强的实用性. |

| Slope stability analysis is an uncertain problem with randomness and puzzle.Using the analysis method of main compositions this paper preferentially selected the characteristic indicators affecting rocky slope stability so as to construct the characteristic parameters for slope stability modes and identify the membership functions of the slope,and establish the calculation method and the fuzzy identification model of slope stability.In the process of simulation modeling,various factors influencing slope sta... |
