| Rock mass is an important groundwork of large complicated structural engineering such as high constructions, bridge engineering, hydraulic-conservancy hinge and so on. There are many discontinuities with different scale, direction and character, the existing of discontinuities not only break the integrity but also affect the mechanics property and failure model of rock mass, it is a very important factor in influencing stability of rock mass. Therefore, it is important to research the property of discontinuity.This paper's researching thread is: researching the property of discontinuity and computer simulation. Based on outdoor investigation, this paper is about analyzing discontinuity's geometric and mechanics property, studying on net work and numerical simulation with computer, with real project, getting geometric and mechanics modal and finding regularity of direction and stress, strain.The following researches are finished in this content:1) Analyzing theory of discontinuity's formation in a project;2) Based on the outdoor investigation, random discontinuity's statistics modal is carried out, with probability method, study on geometric property of random discontinuity.3) 2-D net work model for random discontinuity is formed, with the method of Monte- Carlo simulation.4) Studying on discontinuity's mechanics property, carrying out two kinds of numerical modal with finite element software ANSYS: â‘ original model, â‘¡discontinuities-model (aquiferous state and un-aquiferous state), according to comparison, getting the degree of discontinuity influencing stability of rock mass. |
