| 摘 要： | 通过单样CU三轴试验和多样CU三轴试验、分析，探讨了控制屈服应变和固结排水时间对土抗剪强度的影响．试验结果表明，对于多级加荷试验，第一级控制应变应相对较大，第二级控制应变应稍大，第三级应变应稍小；同时初步得出多级加荷试验下第一级固结度对抗剪强度影响较大的结论．

| Abstract: | Multilevel adding load triaxial test has some advantages, so it is useful for engineering to discuss the application. The effect of controlled strain and consolidation time on soil shear strength is discussed through CU triaxial shear test. Based on the tests and analyses, the useful conclusions that the controlled strain should be rather large in the first shearing stage, and a bit large in the second stage, then small the third are drawn; this paper also points out that the consolidation time in the first stage can affect more on the strength of the soil than time in other stages. |
