岩石断裂断口细观裂纹统计分布规律研究
首发时间:2009-01-13
摘要:岩石是自然界历久育成的产物,是由多种矿物晶粒、孔隙和胶结物组成的混杂体,其中存在各种微裂隙和微孔洞。以往的研究往往是在宏观尺度下进行的,也得出这样的结论:岩石在外部荷载作用下的断裂乃至破坏是由于处于细观尺度的微裂隙的增长和贯通引起的。所以,对于处于细观尺度的微裂隙进行研究分析,对于了解岩石的力学性质有着重要的意义。本文是在前人研究岩石微观结构的基础上,利用Matlab编写处理照片的程序,对大理岩、砂岩、板岩在各种荷载作用下的细观图片进行处理,并得到有益的结论。

An exploration on statistical distribution regularity of fracture surface in rock
Abstract:The rock is the result of a long-term function of nature, and it’s a jumble that composed by many minerals, min-holes and cementation. It used to be researched at microscopical scale, and we have drawn such a conclusion: the rupture and failure of rock under loading is caused by microcracks’ growing and propagating at mesoscale. Therefore, it is helpful to understand the mechanical behavior of rock by microcracks’ investigating. In this paper, former research work on the microcracks of rock is analyzed, and the procedure that done by former researcher is used. By analyzing the images of marble, sandstone and the plank rock, of course, we draw a helpful conclusion.
