EXPERIMENTAL STUDY ON CT CREEP CHARACTERISTICS OF OIL SHALE UNDER IMPACTING DISTURBANCE

摘要：

Experimental research on the creep damage evolution properties of oil shale under impacting disturbance load conditions for the first time were made by using the real time CT testing technique.CT images and CT values for rock cross-sections under different impacting disturbance loading levels were obtained.The aim of the paper is to describe process of oil shale creep damage under disturbance loads and to explore the mechanism of micro-damage.Rock failure is easy to happen suddenly when rock is in or close to limit strength neighborhood during the process of disturbance.This will further lay the theory basis for the prediction of roadways service life and evaluation of geotechnical engineering stability.
