| Abstract: | Based on indoor 1-D consolidation creep te st, a creep function reflec ting nonlinear creep character of soft soil has been set up, the character of re ference time is analyzed and the mathematical method for estimating the referenc e time is presented. Through estimated reference time, another two creep paramet ers were linearly fitted and analyzed. A large number of tests show that the res ults measured are consistent with those estimated theoretically by creep functio n, which demonstrates the rationality of the creep function. |
