摘　　要：根据一维固结理论的解析解建立了便于软粘土路堤工程应用的沉降计算反演预测公式 ,利用前期沉降观测信息反演确定计算参数 ,可以进一步对后期任一时刻的沉降、沉降速率以及最终沉降量进行预测。算例分析表明 。Authors present an observational settlement prediction method for soft clay ground of embankment. The equations of proposed method are derived from the analytical solutions of one dimension consolidation theory. The parameters in equations can be back analysed from the former observational settlement.Then,the latter settlement, settlement rate and last settlement can be predicted.The proposed method is demonstrated to be applicable for actual cases.
