Abstract
Based on the exponential curve fitting method, a new method—geometric progression method for calculating the final settlement of soft clay ground is introduced in this paper. By using the settlement observation curve of a trial embankment of express railway on soft clay ground, two methods were compared and analyzed through the computation of the final settlement. The results showed that the final settlement of soil ground by the exponential curve fitting method calculating is quite often to generate errors. If chosen different time interval Δt and value of time (t), there will be varied final settlements. The new method could avoid such kind of error made by the exponential curve fitting method.
