Settlement characteristics of Coode Island Silt

Sri T. Srithar

Abstract

Coode Island Silt is a Quaternary age alluvial deposit of the Yarra River delta in Melbourne. It is a highly compressible and only slightly overconsolidated deposit, which exhibits significant primary consolidation and creep settlements. This paper discusses the settlement characteristics of this deposit based on laboratory test data and field observations, mostly for a settlement assessment using conventional one dimensional consolidation theory. The rate of creep settlement based on field observations is also discussed.
