| 摘 要： | 本文分析了不同先期固结压力ｐ＿ｃ情况下压缩曲线的特性，提出了ｐ＿ｃ的小值和准小值概念。还考虑了天然孔隙比ｅ＿０的修正，从理论上导出了以准小值为基点的逼近ｐ＿ｃ真值的新方法。用合肥粘土、巢湖粘土试验结果证明，此法求得的ｐ＿ｃ值与ｐ＿ｃ真值是很接近的。

| Abstract: | Characteristics of compressive curves with different preconsolidation pressures p_c,withcon-sideratiOn of rectification of natural void ratio e_o,from Which the conceptions of little value and quasi--little value are analysed. A theoretical Method, in which quasi-little value is regarede as base point toappoach the true value of p_c,is proposed. Results of tests on Hefei clays and Chaohu clays showed thatthe values of p_c obtained by this method are in good agreement with the true value of p_c. |
