昌北千枚岩风化程度的模糊综合评判

Fuzzy Synthetic Evaluation of the Weathering Degree of Phyllitie in Cangbei

道过对昌北千枚岩的现场勘察,选取岩石介质、岩体特征和岩体强度三大类17项影响因素,用AHP法确定各因素的权重系数,最后用两级模糊综合评判方法对昌北千枚岩的风化程度进行了定量评价,并在工程实例中取得了较满意的结果.

Based on geotechnical investigation on phyllitie in Changbei, three influenceing factors, including rock materials, characteristic and strength of rock mass, that have seventeen secondary items, are selected, and which weight are made certain by the Analytic Hierarchy Process. In the end, weathering degree of phyllitie in Changbei is judged quantificationally by fuzzy Synthetic Evaluation, and the method are applied to an work example with satisfying results.
