Research on the Softening and Disintegration Mechanism of Carbonaceous Shale

Abstract:

The microstructure and composition of carbonaceous shale are analyzed by using the scanning electron microscope and x-ray diffract meter, the dynamic characteristics of the disintegrating mechanism and microstructure are also studied. The results show: the connection between mineral particles of carbonaceous shale are destroyed under the action of water, the mineral particles will expand rapidly under the forces of sunlight and temperature change, generating uneven stress and micro-pores. The micro-pores will destroy the structure of rock and make the phenomenon of softening and disintegration. The results could provide a theoretical basis for the filling of carbonaceous shale embankment and the protection of slope.
