| 摘 要： | 采用上海饱和软粘土的重塑土样进行室内长期一维压缩试验,研究了应力历史、加载比以及加载时间对次压缩系数Ca值的影响,得到了上海软粘土Cc与Ca值间的关系,并采用e0与ep的关系来解释Ca值在某些情况下发生变化的现象。

| Abstract: | The coefficient of secondary compress ion C_a is investi gated in the long-term odometer tests. All the samples are made f rom the reconstituted Shanghai soft soils. The test condition includes differe nt stress history, different loading duration and different stress ratio.The ratio of C_c/C_a for Shanghai soft soil is got through the test. The reason why the C_a changes in some conditions is also explained in this paper by inducing the e_0 and e_p concept. |
