随着土工格室在高速公路、河道边坡护坡工程中的逐渐推广,土工格室边坡侵蚀稳定性研究成为研究热点.为有效地对土工格室防止边坡侵蚀的能力进行评价,指导工程实践与应用,通过对土工格室特性、边坡特征以及施工养护等影响因素的分析,建立了土工格室边坡水力侵蚀稳定性评价的指标体系;针对评价等级相对模糊及单项指标评价结果的不相容性问题,引入模糊物元理论,构建了土工格室边坡侵蚀稳定性的模糊物元评价模型,利用层次分析法确定指标权重,最后进行关联分析,根据最大关联原则确定评价等级.研究表明模型将定性和定量相结合,考虑全面,计算简单,易于编程,结合工程实际案例对该模型进行验证分析,评价结果与实际情况符合较好.
With the gradual popularization of geocell in the slope protection of expressways and riverslope slope, the research on geosyncline slope erosion stability has become a research hotspot.In order to effectively evaluate the geocell’s capability of preventing slope erosion, Practice and application of the geogrid, the index system for evaluating the stability of geocell slope stability is established through the analysis of the factors of geocell characteristics, slope characteristics and construction maintenance. In view of the relative fuzzy evaluation level and the evaluation results of single index In order to solve the problem of incompatibility, fuzzy Matter-element theory is introduced to construct the fuzzy matter-element evaluation model of geocell slope erosion stability. The analytic hierarchy process is used to determine the weight of indicators. Finally, the correlation analysis is carried out to determine the evaluation grade according to the principle of maximum correlation. The research shows that the model combines qualitative and quantitative analysis, considers the comprehensive, simple calculation and easy programming, and verifies and analyzes the model with practical engineering cases. The evaluation results are in good agreement with the actual situation.
