Application of the Grey Model in One-Dimensional Long-Term Creep Analysis of Coral Mud From the South China Sea

Coral mud is widely distributed in the South China Sea. Studying deformation laws of coral important to infrastructure development In this article, a one-dimensional oedometer test under near-natural conditions performed. The exponential fitting model, Burgers model and ODGM are used analyse time-strain relationship different vertical pressures. self-fitting accuracy prediction three models pressures compared. Then, number data points was reduced, associated change stability were analysed. study found that has high self-fitting, accuracy, when which describe long-term nonlinear more accurately.
