中文摘要：

运用双曲线法、Asaoka法和灰色理论法3种预测模型，结合广东虎门港区码头工程的现场沉降监测数据，对该工程中用大面积吹填砂堆载预压后的最终沉降趋势进行了预测。结果表明：灰色理论预测效果最好，所得到的预测结果与实际吻合；双曲线法的预测效果次之；Asaoka法预测效果较差，前期和后期的误差都比较大。

英文摘要：

By using hyperbolic method, Asaoka method and gray forecasting model, combined with Guangdong Humen Port Terminal Project site subsidence monitoring data, the final settlement trend of a large area of the project after hydraulic fill sand preloading is predicted. The results show that Grey theory got the best prediction results and it was consisted in the actual, but the hyperbolic method to predict the effect followed, Asaoka method to predict less effective, early and late error was relatively large.
