ABSTRACT

Marine clay generally exhibits poor physical and engineering properties. To study the compressibility and creep behavior of Zhuhai marine clay, the incremental loading test with a 4-day duration for each loading step was conducted on undisturbed and remolded samples. The Cc and Ca are carefully calibrated by using the void ratio increment at the end of primary consolidation and in the first cycle of secondary consolidation, respectively. A linear relationship between the compression modulus and the initial void ratio is established for undisturbed Zhuhai clay. The experimental results indicate strong rheology for the Zhuhai marine clay. Moreover, given nonlinear creep, the decline in Ca during the secondary consolidation is significant. The data presented in this paper provide a foundation for the theoretical research of viscoplastic characteristics in the future.
