Software Development Based on StereoAnalytical Method for Block Theory and Its Application to Watertight Oil Storage

Abstract:

This paper presents the theory basis and programming outline of software Block1.0 employed to determine removable blocks based on the stereoanalytical method for block theory,and the result of the software proves reliable and efficient in comparison with that of stereoanalytical method.In addition,after a detailed investigation and study on geologic conditions of Jinzhou watertight oil storage cavern by using Block1.0 and Unwedge software,respectively,all removable blocks relaed to each excavation plane of Jinzhou watertight oil storage cavern were found and the magnitude of the removeable blocks with respect to the distribution of discontinuities and the position of excavation planes was systematically calculated.The results show that Block1.0 can provide a more reliable basis for the smart reinforcement design of the cavern and be more feasible.
