| 摘 要： | 用总应力法研究了应力路径对陇西Q3原状黄土的固结不排水剪强度的影响。试验基于正交设计，考虑了含水率、固结比、固结末径向应力和剪切路径4个因子、4种水平。试验结果表明，当黄土各向异性程度较小时应力路径对黄土的固结不排水抗剪强度有一定影响；基于正交设计的黄土三轴固结不排水剪试验的破坏点与普通三轴固结不排水剪试验（均压固结常规剪切）得到的破坏点处于一个条带内。黄土强度随含水率的变化规律与普通三轴固结不排水剪试验的相同。

| Abstract: | A series of consolidated un-drained triaxial tests with equal consolidation ratio and equal shear are done for undisturbed loess Q3 samples from Longxi region of Gan-Su province.The total stress method is used in study.The test results indicate that the stress path has certain influence on the loess shear strength when loess has some different properties in different directions.The destroy points of the stress path tests,together with those of regular triaxial tests,distribute in a strip of area. |

| Keywords: | shear strength undisturbed loess stress path total stress method |
