Study of preferred structural plane of subgrade slippery rock based on fuzzy comprehensive evaluation
摘要
Abstract
The preferred structural plane theory has been applied to geotechnical engineering praaice 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 witl: 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 obj eaivity and compatibility in the calculation of engineering preferred structural plane and greatly improves the calculation accuracy and efficiency.关键词
