摘要:
针对乌尉(乌鲁木齐至尉犁)高速公路地处高寒、高海拔、高地震烈度区,地质环境条件复杂的特点,提出一种基于多判据的边坡稳定性模糊综合评价方法。首先,分析研究三高地区公路沿线工程地质条件、边坡岩体结构特征及其变形破坏模式。在此基础上,以TSMR评价体系为框架,考虑地震荷载对边坡稳定性的影响,引入地震作用影响系数β,建立了适用于“三高”地区公路边坡岩体质量分级体系THRSMR;基于边坡可靠性分析理论,归纳总结Monte Carlo法的操作步骤,并借助GEO-SLOPE软件,给出各研究边坡的可靠度指标与失效概率;最后,将定性评价、极限平衡分析、可靠度分析和数值计算的结果分别作为基础指标,采用模糊综合评价方法对每一边坡的边坡稳定性,给出进一步量化结论。其结果对类似地区高速公路边坡稳定性评价具有一定的参考价值。
Abstract:
A fuzzy comprehensive evaluation method for slope stability based on multi-criteria is proposed for the characteristics of Wu—Yu highway, which is located in the frigid, high altitude, high seismic intensity area with complicated geological environment condition. Firstly, the engineering geological conditions, the structural characteristics of the slope rock and the deformation and failure modes of the slope along the highway are analyzed. The TSMR evaluation system is taken as the framework, the influence of the seismic load on the slope stability is taken into account, and the seismic coefficient β is introduced and the slope rock mass classification system THRSMR suitable for the “three high” highway is also established. Based on the theory of slope reliability analysis, the steps of the Monte Carlo method are summarized, and the reliability index and failure probability of each typical slope are given by GEO-SLOPE software. Finally, the results of qualitative evaluation, limit equilibrium analysis, reliability analysis and numerical calculation are taken as the basic indexes, and the fuzzy comprehensive evaluation method is used to give further quantitative conclusions on the slope stability of each slope. The results have certain reference value for highway slope stability evaluation in the “three high” region.
