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。
The extent and homogeneity of fault structure and tectonics of rock mass are the important factors that affect the type of rock mass structure, the quality of rock mass and the stability of rock mass and the comprehensive zoning of rock mass. Therefore, the quantitative evaluation of rock mass fault tectonic development has Important engineering significance. Taking the Permanent Ship Lock Slope Project of the Three Gorges Project as an example, this paper systematically discusses the assessment methods of the fracture development degree of the engineering rock mass, the principle of determining the quantitative evaluation index and the grading standards of the fracture development degree. The research shows that according to the characteristics of fault structure development of rock mass, the comprehensive application of multi-level fuzzy comprehensive evaluation and artificial neural network is an effective method to evaluate the development degree of fault structure in rock masses.
