Three Dimensional Random Structural Model of Karst Rock and its Application

Abstract:

Karst caves determine the engineering characteristics of the whole rock in a large extent. A methed to simulate karst caves is described in this paper. Firstly, three-dimensional mathematic description of the geological mass in which karst caves lies is given. Secondly, the determination of the shape and size of ellipsoids which are adopted to simulate karst caves is introduced in detail. The mathematic modeling of three-dimensional random caves is discussed simultaneously. Thirdly, a real three-dimensional random structural model of karst rock based on actual observation records is provided. Lastly, the above model used for the leakage analysis of the karst rock is discussed. The research results illustrates that the Mathematic model for three-dimensional random caves of karst rock put forward in this paper can be very helpful to leakage analysis on Karst rock.
