Brittle strength of basaltic rock masses with applications

1993-6-25  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.

CORRELATION BETWEEN UNCONFINED COMPRESSIVE

2019-4-21  tensile strength is very fast comparing with unconfined compressive strength. Material was created using plaster of Paris and water to simulate as jointed rocks. Three joint conditions were considered for evaluating the unconfined compressive strength using indirect tensile strength (joint orientation, joint roughness and number of joints).

Limits on strength and deformation properties of jointed

A study of strength and deformation measurements for basaltic rocks, along with consideration of the influence of fracturing using a rock mass classification system, documents the range of brittle response for basaltic rock masses. Although basalts vary widely in composition and other physical factors, many of the properties of a basaltic rock mass appear to vary within a factor of about 10
