Abstract:
In order to reveal the dynamic response rules of soft soil foundation beneath low embankment under traffic load,the in-situ tests for the dynamic pore water pressure in soft soil stratum were conducted.The distribution laws of pore water pressure under different embankment thickness and different running speed were analyzed.In addition,the additional settlement of soft soil stratum under long-term traffic load was analyzed by numerical simulation.The results showed that embankment fills could reduce the dynamic effect of traffic load.The dynamic response of underling soft soil foundation increased with the decrease of the embankment thickness,and the dynamic pore water pressure declined with the depth increases.Moreover,the long-term addition settlement of soft soil foundation could be expressed as exponential function of time under traffic load.
