cohesive strength of basalt rock

8. STRENGTH OF SOILS AND ROCKS

The tensile strength of soil is very low or negligible and in most analyses it is considered to be zero. In contrast a number of direct or indirect tensile strength tests are commonly carried out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force.

Dynamic compressive properties of Kalgoorlie basalt rock

Nov 01, 2020· For basalt rocks, Malik et al. 12 investigated Deccan basalt rock and found the dynamic compressive strength between about 170 MPa and 260 MPa at a strain rate of about 400/s to 1600/s. Lindholm et al. 13 found a much lower dynamic strength of about 110 MPa to 125 MPa at a strain rate of about 600/s and 1100/s for Dresser basalt rock.

Limits on strength and deformation properties of jointed

Jan 01, 1995· A measured deformation modulus for ambient pressure in the vertical direction, 20 GPa, is 1.5–3 times larger than that in the horizontal directions, 13.5 and 6.5 GPa, reflecting strength anisotropy due to column or block geometry for one particular basalt. Values of tensile and cohesive strength for the basaltic rock mass are generally one to

face easily, indicating the low strength of this rock. However, because the rock contains no frac-tures, it has a significant cohesive strength in addi-tion to a moderate friction angle. Therefore, it was possible to cut a stable, vertical face to a height of FIGURE 14-1 (far left) Planar failure on continuous bedding surface dipping out

Brittle strength of basaltic rock masses with applications

Values of tensile and cohesive strength for the basaltic rock mass are approximately one to two orders of magnitude lower than corresponding values for intact basalt. Temperatures comparable to those at the Venus surface may slightly increase the deformation modulus but decrease the compressive strength of the rock

STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1

In general, rock mass strength depends on the strength of intact rock and the strength of rock discontinuities.
