Jun 25, 1993 Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material. Experimental results for elevated temperature extend the applicability of these parameters to the near-surface environment of Venus.

Aug 01, 2013 Porosity is a significant physical feature of rocks due to water absorption that causes decrease in the strength. The basalt of the study area can be described as “highly porous” and ignimbrite as “extremely porous” according to the classification by Anon (1979).The average UCS of basalt is determined as 26.65 MPa.For the ignimbrite, the lowest UCS is observed in the black
