It is found in this paper that fractured zones of rock masses in high stress area are larger than those of others,but their horizontal displacement does not increase obviously.

Through comparative analysis, this paper expounds the feasibility of adopting roofbolt supporting technique in coal road of high stress areas, and introduces the forms, technical parameters and construction techniques of roofbolt support.

The constitutive relation of an Mg-Al Alloy under uniaxial compression at high strain rates is fitted and checked using the SHPB(Split Hopkinson Pressure Bar)experimental results and the numerical simulation based on the fitted constitutive law of the specimen.

In this paper, the glass-epoxy 3-D braided composites are tested under high strain rates(4000 s -1,5000 s -1,6000 s -1) with SHPB(the split Hopkinson pressure bar)for dynamic response, The experimental results show that the glass-epoxy 3-D braided composites are strain rate sensitive materials.

To objectively describe the behavior of confined concrete under high strain rates the loading history has to be taken into account.
