摘　　要：基于路基沉降实测资料,用双曲线模型对某高填路基的沉降变形进行了预测分析。实测资料和理论分析表明:双曲线模型简单易行,可对高填路堤进行沉降预测尤其是对中后期的沉降预测,并得到较为满意的结果,能预测路基最终沉降值从而判断路基沉降稳定状况。On the base of the monitor datum of subgrade settlement, this paper use the hyperbolic method to predict and analyse the settlement of a high backfill subgrade. The actual measurement results and theoretical analysis showed that the hyperbolic method is a simple solution to predict settlement of high backfill subgrade and achieve more desirable results, especially in the subsequent phase. This method can predict final settlement and iudge settlement stable stability of subtwade.
