摘要：

优势结构面理论已逐渐在岩土工程中应用。首次将物元模糊耦合评价方法应用于岩体优势结构面的确定中，提出基于物元可拓法的模糊综合评判模型。该模型把易滑岩层的结构面状况作为物元的事物，以结构面的各项几何、物理参数指标及其相应的模糊量值构造复合模糊物元，通过关联度计算，实现对优势结构面的判定。该模型能很好地处理易滑岩层优势结构面计算过程中岩土体性质、规模、产状、分形优势指标及活动状况等不确定的模糊因素，为路基易滑岩层优势结构面的评判提供了一种新途径。此方法克服了传统方法确定优势结构面只考虑数量优势而忽略质量优势的缺点，使结构面评价更合理。通过介绍这种方法的基本理论和操作步骤，并在一工程实例中加以运用。可以看出，该模型有效地保证了工程优势结构面计算中评判的客观性和指标的相容性，大大提高了计算的精度与效率。

Abstract:

The preferred structural plane theory has been applied to geotechnical engineering practice gradually. The fuzzy comprehensive evaluation model based on matter element method is proposed and applied to determine the preferred structural plane of rock for the first time. The states of structural plane are regarded as the objects of matter element; geometric parameters and physical parameters for evaluation as well as the corresponding fuzzy values are used to construct the composite fuzzy matter elements. The evaluation of preferred structural plane is made by calculating the relevancy. The model can deal with the uncertain factors during the preferred structural plane calculation, such as rock and soil characters, scale, occurrence, fractal indices and active state; the model provides a new way for evaluating the preferred structural plane of slippery rock. The shortcomings of traditional methods, only considering the quantity predominance but without the quality predominance are overcome in the model; and the evaluation of rock structural plane is more reasonable. This article introduces the basic theory and calculation steps of the fuzzy comprehensive evaluation by matter element method. Through introducing basic theory and operating steps, a case study is given. The model effectively ensures the objectivity and compatibility in the calculation of engineering preferred structural plane and greatly improves the calculation accuracy and efficiency.
