Özet
Discontinuities play a crucial role in the stability of any engineering structures such as open pit slope, highway wall, etc. Because the discontinuities are mechanically weak zones and failures occurred thought discontinuity surfaces and intersection lines which are bounded rock blocks. Therefore, the characterization of rock mass and the stability analysis based on this evaluation requires a deep understanding of the discontinuity geometry (i.e. Dip and dip direction). In order to assess the global quality of a rock mass, several authors proposed the use of geotechnical classifications for a long time. All of the classifications are including several geometric parameters in several degrees. Intersection lines between discontinuity surfaces and points of them on the visible surfaces of any engineering structure that excavated rock mass may also be indicators of any instability. This paper describes a new approach to modeling of intersecting lines and points as the evaluation of the instabilities of an engineering structure which excavated in rock masses. This study includes a series of derived linear equations to describe the orientation of intersecting lines, the location of exposed intersection points and finally statistical distributions of the obtained results. Kernel Densities Estimation (KDE) was used as a tool for the statistical analysis. This analysis carried out as the contouring intersection points by selecting critical intersection lines according to friction angle of discontinuity surfaces. The model seems to be a practical tool for assessing of rock mass instabilities.To run the model, dip, dip direction and spacing values are adequate. © 2016 Taylor & Francis Group, London.
