摘要: 本文利用无侧向变形的单向压缩试验仪,对原状和重塑上海软土进行了压缩试验和流变试验,研究了不同压力和超固结比对次固结系数的影响以及压缩特性和次固结变形特性的关系。试验结果表明,原状上海软土的次固结系数随着压力而变化,而重塑上海软土的次固结系数随压力变化不大。上述研究得到的结论及相关参数可为工程实践、上海软土流变模型的建立提供参考数据。

Abstract: One-dimensional compression tests and secondary consolidation tests on undisturbed and remolded Shanghai soft clays were conducted using oedometer. Effects of the applied pressure and over-consolidated ratio on the coefficient of secondary consolidation and correlation of compression characteristics and secondary consolidation characteristics of Shanghai soft clay are studied. It was found that the coefficient of secondary consolidation of disturbed Shanghai soft clay changes with the applied lo...
