摘　　要：利用Verhulst模型和双曲线法变权分配组合建立了变权重组模型,并应用于普通压实路基及回填路基的工后沉降预测,结果显示大大提高了预测精度,而且在普通压实路基工后沉降预测具有更好效果。In this paper,the Verhulst model and the hyperbola variable weight allocation combination are used to establish a variable weight reorganization model.It is applied to post construction settle-ment prediction of ordinary compacted subgrade and backfilled subgrade.The results show that the prediction accuracy is greatly improved,and the prediction of post construction settlement of ordinary compacted subgrade is better.

关 键 词：路基工后沉降预测 VERHULST模型 双曲线法 变权重组模型
