Creative and application of Nenjiang opal shale super fine study and application in ABS;

We did radio nuclide 131 I transport diffusion experiment and permeability-dispersion experiment in shale media.

In the paper, there is an introduction of the technology of calcinating portland clinker in the mechanical shaft kiln using carbonaceous shale partly in place of clay batdh .

Based on the trial section of high embankment engineering of an airport in Southwest China,the impact compac- tion property of carbonaceous shale as a primary filling is studied.

Based on construction monitoring data of the Shaziya tunnel in western Hubei province, the deformation laws with time of layered carbonaceous shale tunnel are analyzed and the corresponding equations of the deformation laws are proposed.

4 incline shaft of the Wushaoling Super Long Tunnel crosses multiple-site deep-buried carbonaceous shale strata,and different stress-deformation properties are presented in this stratum due to different geological structure and characteristic.

The 1# exit straight tunnel of Songgui is passing through the deep-buried carbonaceous shale,which presents different forms of stress-deformation in the progress of construction,for the influence of both geologic formation and characteristics of carbonaceous shale.
