福清新厝公路拓宽海堤段海堤内侧采用分级加载进行路基施工填筑软基加例处理,通过3个断面监测数据分析,最大水平位移日变量为2.28mm/d,最大沉降速率为5.97nm/d,各测点的沉降速率和水平位移均在安全控制范围之内。至监测末期最大总沉降量占淤泥层厚度7%,海堤地基固结度76.3%~85.0%,但尚有10.9~15.8mm的工后沉隆量,地基沉降变形将持续一段时间。

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.
