摘要
岩体裂隙面形态特征评价方法有立体评价法、垂直剖面法、迷向均匀随机线法、角分布法、余纬度分布法等。评价的主要内容集中在裂隙面粗糙度和线粗糙度方面,并建立了一系列的理论模型。实践证明,这些方法的评价结果均较接近,均能较为真实地反映裂隙面的形态特征。然而基本资料的获得以及评价方法的可操作性都有一定的难度。
Estimations of the morphological characteristics of fracture surface in rocks include the stereological estimation,the vertical section method,the method of the isotropic uniform random line,the method of the angular distribution,the method of the colatitude distribution and so on.The main estimation is the rugosity and the linear rugosity of the fracture surface.A set of theoretical models has been built.It is shown that the results of estimations approximate to the measured values,and can express the morphological characteristics of fracture surface.But,it is ifficult to obtain the initial data and to implement the method,especially,the measuring equipment of high quality is required.
