Muddy clay is common foundation soil in wharf engineering，and its creep properties are closely related to the stability of wharf foundations.To study the creep mechanical properties of muddy clay under different confining pressures，we carry out consolidated drained triaxial compression creep tests.On this basis，we introduce the Mesri and Log-Modified models to simulate the creep mechanical behavior of muddy clay，obtain the empirical creep models，and compare the identification effects of the two models.The results show that with the increase in axial pressure under the same confining pressure，the axial strain increases gradually，and the initial and steady creep rates show a linearly rising trend.With the same loading level，the increase in confining and axial pressure promotes the growth of axial strain，and the initial and steady creep rates under high axial and confining pressure are always greater than those under low axial and confining pressure.The isochronous axial pressure-strain curve of muddy clay is approximately hyperbolic and has prominent nonlinear characteristics.Moreover，the identification effect of the empirical Mesri creep model is better than that of the empirical Log-Modified creep model.
