软土固结的非线性特征与沉降分析

首先以实测沉降数据为基础，采用正反演分析和时间序列分析相结合的办法，证明了一维固结非线性理论较一维固结线性理论更符合工程实际。其次，采用一维固结非线性理论对某高速公路软基的沉降固结特性进行了分析，最后提出了采用比例系数法定量地分析超载对降低工后沉降的作用，并对某高速公路软基的沉降进行了分析。

Non-Linear Consolidation Characteristics and Settlement Analysis of Soft Soil

On the basis of actually monitoring data and by the method of direct-inverse analysis and time series analysis, it is proved that the theory of one dimensional non-linear consolidation more accords with the engineering practice than the linear theory. The settlement of a highway is analyzed by the non-liner method(the ratio method) and a new method put forward to evaluate the effect of surcharge.
