中文摘要：

现有计算软土次固结变形的常用方法是不考虑荷载对其影响的。大量的试验表明荷载对次固结有较明显的影响。本文对次固结变形与荷载的关系进行了较详细的探讨，并着重研究了正常固结土的次固结特性，且对其规律进行了总结和分析。结果表明：对超固结土，次压缩系数随荷载增大而增大；对正常固结土，次压缩系数随荷载增大而减小。在此基础上提出了正常固结土次固结沉降量随固结压力变化的计算方法。

英文摘要：

The conventional method of computing the secondary consolidation of soft soils does not reflect the influence of load. However, it is shown that the secondary compression is obviously influenced by load. The relationship between the secondary consolidation deformation and load were discussed and the characteristics of the secondary consolidation of normally consolidated soils were emphansized in discussion, and some rules were concluded and analyzed. The results were as follows： for the over-consolidated soils, coefficient of the secondary consolidation increased with load; for normal-consolidated soils, it decreased with load. Based on the results, the computation method for deformation of the secondary consolidation reflecting the influence of consolidation pressure was developed.
