Summary

The Neranleigh-Fernvale strata underlie much of the Brisbane CBD and surrounding areas, with many high-rise buildings and tunnels founded in these rocks. The intact rock strength is impacted by factors such as lithology, weathering, and loading direction. Weathering characteristics vary locally, with a profile often extending 3-6m below the surface, but can be more complex and lithologically controlled. The strength of the rocks depends on the degree of weathering, with a convincing correlation between weathering and strength. The unconfined compressive strength (UCS), point-load strength index, and Brazilian tensile strength test results show a general strength relationship, with UCS being the highest and Brazilian tensile strength being the lowest. The degree of weathering has a significant impact on the intact rock strength, with fresh rock being the strongest and extremely weathered rock having soil-like properties.
