bimrocks
What is this web site? This site is an accessible
source of information on bimrocks for geological and
geotechnical practitioners. Currently, there is no
other site like this one.
What are bimrocks? Bimrocks are block-in-matrix
rocks, mixtures of stronger blocks of rock surrounded
by weaker matrix rocks. Bimrocks are geologically,
spatially, and mechanically heterogeneous. Bimrocks
include melanges, fault rocks, weathered rocks,
lahars and some "rock/soil mixtures."
So what? Bimrocks universally frustrate the
economic and accurate characterization, design and
construction of civil engineering works.
Who cares? Bimrocks are troublesome to
geotechnical engineers, geologists, contractors and
owners. Attorneys offer to resolve the troubles.
