This paper presents some of the key characteristics of carbonate sediments from nearshore and offshore, Western Australia. Emphasis is given on how the different formation conditions, in terms of their depositional environment, physical characteristics and grain strength affects the behaviour of these sediments.
The characteristics discussed in this paper comprised of basic properties including grain shape and size, onedimensional compression response and strength associated with soil remoulding (soil sensitivity) and cyclic loading (pre-peak and post-peak cyclic response). It is demonstrated throughout the paper that the characteristics of carbonate sediments depends on the depositional environment. Carbonate sediments deposited in low energy deepwater environment are often found to comprise very fragile and often hollow soil particles. These sediments are highly susceptible to particle crushing and often provide soil parameters that are well outside the general range obtained for other standard non-carbonate sediments.
