Soft soils have been utilised intensively for urbanisation and civil infrastructural development due to the scarcity of proper soils for construction. Soft soils themselves exhibit many engineering problems, such as large settlement which occurs in long time after construction. There are a large number of studies carried out to analyze that time dependent behaviour of soft soils, resulting in the variety of theories and models. The mechanism of creep deformation is the background to propose a model for predicting the long term settlement. However, there has been no unique explanation for the behavior of soils, leading to different theories of settlement analysis and prediction. There exist two main hypotheses for settlement calculation, Hypotheses A and B, distinguished based on different elucidation about creep mechanisms. From the existing research studies, this paper aims to discuss five mechanisms of creep including (i) the breakdown of interparticle bonds, (ii) the jumping of bonds of molecules, (iii) sliding movement among particles, (iv) the water drainage in double pore system, and (v) the structural viscosity. In this study, according to the explanation of creep mechanisms, the difference of the two hypotheses will be provided. This paper also suggests a creep mechanism based on the combinations of the explained mechanisms.
