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.

ABSTRACT: Understanding and predicting the intact strength of rock is very important in design of foundations, tunnels, and in other engineering projects. The presence of vesicles within basalt has a direct impact on the unconfined compressive strength (UCS) of the intact rock.

This particularly applies to metamorphic rocks as illustrated in Fig. 8.4. Strength testing of rock is discussed further by Franklin and Dusseault (1989). 8.2 TENSILE STRENGTH The tensile strength of soil is very low or negligible and in most analyses it …

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can …
