摘　　要：从一维固结理论出发,建立了数学模型,经过严格的数学推导,证明了在线性加载或近似线性加载情况下,沉降 时间曲线呈"S"形。Based on onedimensional consolidation, the mathematical model is established and, according to the rigorous deducing, it is proved that st curve appears 'S' shape when the load is increased linearly, which is similar to real construction process.

关 键 词：沉降-时间曲线 固结 线性加载 数学模型 预测 土体
