| 摘 要： | 基于大量实测软基沉降监测数据，分析了恒载预压期长短对Asaoka法推算沉降的影响，发现用该法推算珠三角地区软基沉降所需要最短恒载预压期为4个月；提出了Asaoka法推算软基最终沉降的修正公式，可减小由预压期较短而引起的沉降推算偏差。

| Abstract: | Based on the large field testing settlement data of Dongguan-Gangkou Road trial section, the influence of lasting carry preloading time on settlement calculation by Asaoka method is analyzed, which predicts the soft ground embankments settlements in the Pearl River tri-angle areas that need four months lasting preloading time at least. A formula for correction coefficient of ultimate settlement of soft soil subgrade with Asaoka method is proposed to diminish the deflection of the settlement prediction for the shorter preloading time. |
