Embankment Deformation Surveying and Calculation Analysis in the Dynamic Drainage Foundation Treatment

According to the dynamic drainage consolidation foundation treatment application in the road embankment engineering,the embankments deformation surveying were executed.The embankment settlement surveyed results showed that the embankment settlement increase quickly at first,then slowed down to 675mm,and the settlement decreased along with the depth.There was lager deformation at the depth 4m~6m where the silty soil stratum existed,which showed the silty soil's low shear resistance.A new total settlement calculation method for dynamic drainage consolidation foundation treatment was presented in this paper and the parameters of this method were identified.The calculated total settlement value was 651.83mm and the surveyed total settlement value was 675mm,there was a good agreement between the calculated value and the surveyed value,which testified this method's feasibility.
