摘　　要：从土体本构关系出发,证明了在线性加载或近似线性加载情况下(这和公路实际加载相类似),沉降一时间曲线呈S形,并由此建立了新的沉降一时间预测模型,工程应用证明了该模型的合理性。Based on stress-strain relationship of soil, the proof is made that S-t curve appears S shape when the load is increased linearly, which is similar to contruction process. A new model of forecasting the relation of settlement-time is presented. Case history shows the rationality of the method.
