摘要： 东莞虎门港区E号路软基采用塑料排水板堆载法处理，通过对该软基沉降的监测，整理出了监测时间内沉降随时间变化的曲线图，并用多种方法推测该处的最终沉降。依据实测曲线推算出的沉降值与用ABAQUS分析软件计算的沉降值结果接近，表明了依据实测资料求解最终沉降的可靠性和用ABAQUS计算塑料排水板堆载预压法沉降问题的可行性。

Abstract: Settlement monitoring of an embankment on soft soils improved by preload with Prefabricated Vertical Drains (PVD) method underneath Road E, Humen Port in Dongguan, allowed the ultimate consolidation settlements at various locations to be predicted by different methods. The ultimate settlement deduced from the observed data is compared with the value predicted from a numerical analysis using ABAQUS. The results suggest that it is feasible to predict the ultimate settlement by ABAQUS simulations. The results also allow evaluation of the reliability of ultimate consolidation settlement values predicted from observed settlement data.
