| 摘 要： | 边坡工程是一个复杂的系统工程。边坡的稳定与否直接关系到其防护工作的程度。因此,如何有效、合理地判断边坡的稳定性对整个工程的经济与社会效益极为重要。影响边坡稳定的因素众多,判断其稳定与否应考虑各因素的综合效果。论文运用模糊理论中的多因素综合评判模型对某高速公路边坡的稳定性进行研究。通过全面考虑影响因素,建立相应的评判因素集及单因素评判矩阵,运用专家评判法和判断矩阵法确定出各因素的权重。最后通过多层次模糊评判得到该边坡的稳定性评判结果。研究证明,该法在边坡稳定性分析评判中是切实可行的。

| Abstract: | Slope is a complicated systems engineering.The slope stability affects the depth and span of the slope protection,so,how to estimate the slope stability effectively and reasonablely is very important to the economy and society benefit of the slope engineering.Because there are a lot of the factors affecting the slope stability,we can't use only one factor,and should consider the entire target when evaluating the slope stability.This paper uses the fuzzy synthesis evaluation based on the fuzzy theory to study the slope stability.After analyzing the slope we find the aggregate of the influence factor, and construct the evaluation aggregate and the evaluation matrix of the single factor,then,the weights are determined by the experts marking method and the analytical hierarchy process.Finally,the evaluation result of the slope stability is drawed through the model of the multi-level fuzzy synthesis evaluation.The example proves the validity and practicality of the method.This method can solve the question of the slope stability effectively. |
