A Study of Simulation about Crack-lines on the Rock Wall

Abstract

To evaluate about the safety of the space under the ground, it is made use of the Finite Elements Method and etc. But, on thier analysis model, enough informations are not considered about the data by the geological surveies. Normally, the mechanical charactaristics of rock masses are influenced by existence of faults, joints and cracks.
This study has the new suggestion to deal this problem. In situ, the geological surveies give a many informations about the earth. As one of them, there are the survaies about the distribution of the crack lines on the heigh wall. Now, it generalize the data with length and thier directions as the Fractal phenomena. And a new technique to simulate about crack lines on a plane has been developed. The study is based on a consideration of Fractal Criterion with the structure of self-similarity and contraction mapping.
It is one of useful technique to convert from the analogic-data to digitals in geology.
