    FUZZY HIERARCHY ANALYSIS FOR TREATMENT EFFECT OF COMPLEX CUTTING HIGH SLOPE DISEASE

    • 摘要: 双永高速公路K227滑坡由于地形高陡、地质复杂、环境敏感、施工困难等因素成为典型的复杂超高路堑边坡和项目建设及运营养护的关注焦点。为评价该边坡病害治理效果,在长期参与其治理过程的实践、思考、评价和监控基础上,从地形条件、地质条件、环境条件、应力调整和变形控制等方面构建复杂路堑高边坡安全评价指标体系、特征状态量化标准和各评价指标权值。结合模糊综合评判法、专家权威系数修正和最大隶属度原则,建立复杂路堑高边坡安全评估的模糊层次评价模型和评估方法,并与极限平衡法和有限元法计算成果、以及治理前后的现场变形迹象调查和持续性变形监测结果对比分析,对K227滑坡病害治理效果进行综合评判,并证明其是评价复杂路堑高边坡病害治理效果的有效方法。

       

      Abstract: For its high and steep terrain, complex geology, sensitive environments and construction difficulties, K227 landslide of Shuangyong highway became a typical complex cutting ultrahigh slope and the focus of concern during constructing and maintaining. Based on practice, thinking, evaluation and monitoring in the long-term governance process of participation, through the analysis of terrain conditions, geological conditions, environmental conditions, stress adjustment and deformation control, the safety evaluation indexes system of the slope was built. The weight of each index was calculated by analytic hierarchy process. With fuzzy comprehensive evaluation method, expert authority factor correction and maximum subordination degree principle, the comprehensive model for slope safety evaluation was established. Meanwhile, the calculation of limit equilibrium method and finite element analysis, and monitoring records in site had confirmed the safety evaluation result. Therefore, it was proved to be an effective method for evaluating treatment effect of complex cutting high slope disease.
