Abstract: Triaxial creep test with non-drainage of soft clay in Zhanjiang area was systematically carried out,the complete creep curves were achieved under different confining pressures and different stress states,both creep curves of staged loading and creep equal-time curves were established by linear Boltzmann overlapping principle as well as Coordinate Translation.Broken line form of creep equal-time curves showed specific creep properties of soft-soil in Zhanjiang,the stress-strain relationship of th...
