Review of Compression Properties of Coral Sands

Abstract

Abstract. The compressibility properties of coral sands have been realized from indoor experiments and in-site construction. In order to summarize the compressibility of coral sands, this paper reviewed the previous researches and gave some reference for the following researches. It is found that: 1) the compression curve of coral sand is very similar to that of normally consolidated clay and there are two parts of the curve, arc part and linear part; 2) The slope coefficient of the linear part becomes larger as the initial void ratio of the coral sand increases and all of them lies into the same final state as long as the compress stress is large enough.
