cohesive strength of basalt rock

Cohesive Strength Of Basalt Rock

2020-11-1 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.

The maximum horizontal force was greater than that of the vertical force. When the cohesive strength reached 2.0 MPa, the maximum horizontal force was closed to the vertical force. The result showed that the integrity and stability of the double-layer rock plates increased with the layer cohesive strength increase between two rock plates.

1996-9-1  The basaltic rock mass is also weaker in tension, .2 to 2 MPa, than the intact basalt, -14 MPa. Similarly, the unconfined compressive strengths are reduced by com- parable amounts, from about 160 to 20-60 MPa for the welded tuff, and from 260 to 10-65 MPa for the basalt. Cohesive strengths of the rock masses are also reduced significantly.
