ABSTRACT: An earth fill dam exhibited significant deformation in the upstream side after 50 years of satisfactory operation. Studies in this dam revealed that this was brought by creep movement. However, the studies were unable to simulate the strain softening of the soil coupled with time-dependent creep deformation. To address this, the use of Time-dependent Model for Structured soils (TMS) was proposed. It is an incremental plasticity time-dependent constitutive model based on the Modified Cam Clay. It incorporates the principles of critical state soil plasticity which can systematically emulate the primary, secondary and tertiary creep phases. The research would allow the assessment of the long-term slope stability of water-retaining structures and the development of remedial measures for existing earth fill dams that do not satisfy modern long-term slope stability dam safety requirements.
