    摘要
  • 摘要: 岩体断裂构造发育程度及其均匀性是影响岩体结构类型、岩体质量优劣及岩体稳定性分析以及工程岩体综合分区利用的重要因素, 因此岩体断裂构造发育程度的定量评价具有重要的工程意义。本文以三峡工程永久船闸边坡工程为例, 系统地讨论了工程岩体断裂构造发育程度的评价方法、定量评价指标的确定原则、断裂构造发育程度的分级标准等。研究表明, 根据岩体断裂构造发育特点, 综合运用多层次模糊综合评判法和人工神经网络技术是评价工程岩体断裂构造发育程度的有效方法。
    Abstract: The development degree and homogenity of fault structures in a rock mass are the significant factors affecting structure types of the rock mass, rock mass quality, stability and comprehensive utilization of the engineering rock mass. Thus,it is important to estimate quantitatively the development degree and grade fault structures in the engineering rock mass. The permanent shiplock slope engineering in the Three Gorges Project is taken as an example, the methods to evaluate the development degree of fault structures are discussed systematically in this paper. A grade scale and the principles to decide indices are put forward. Results show that the comprehensive fuzzy evaluation and the artificial neural network are feasible to estimate the development degree of fault structures in rockmass based on regularity and patterns of the fault structure.
