中文摘要：

利用模糊信息优化处理的基本理论（模糊近似推论、信息扩散、信息集中），建立了加筋高路堤稳定性的分类及评价其指标的信息矩阵，获得了加筋土高路堤稳定性评价的信息扩散模型。通过对北张沟加筋高填路堤进行的稳定性分析，表明该模型能较全面地考虑加筋高路堤边坡稳定性的影响因素，评价结果合理。

英文摘要：

A general information matrix of classification and evaluation indices for the reinforced high embankment, which were based on the fundamental theory of fuzzy information optimization （fuzzy approximate reasoning, information diffusion and information integration） was set up. The model was used to analyze the stability of reinforced high embankment in Beizhang Gully area, and the result accorded with the facts, which verified that the effecting factors of the stability of reinforced high embankment can be described more comprehensively by the fuzzy information optimization method and the result is reasonable.
