| Abstract: | The stage loading was adopted to reinforece the fill soft soil subgrade of subgrade construction in the levee inner of highway widening of Xincuo County. Based on the analysis of the three sections monitoring data, the maximal horizontal displacement VPD reached 2.28mm/d and the maximal settlement velocity reached 5.97 mm/d, so there were in the safety range of settlement velocity and horizontal displacement in survey points. The maximal total settlement values constituted for 7% percent of the silt layer thickness monitoring end, and the seawall foundation degree of consolidation constituted from 76.3% to 85.0%, but the settlement values was from 10.9 to 15.8mm after the construction, so foundation settlement deformation will continue for some time. |
