| 黄土工程中存在着大量平面应变问题，但目前仍采用常规三轴实验的处理方法，通过对西安理工大学真三轴仪进行改装，实现平面应变实验，对比分析不同含水率、不同固结围压下平面应变实验与常规三轴实验的差异。研究表明：含水率对两种条件下土体的强度影响较大，围压次之；在相同条件下，平面应变条件下土体的强度要明显大于常规三轴下的土体强度，说明以往对平面应变问题的处理偏保守。研究对设计和施工起到了一定的指导作用。 |
| 英文摘要: |
| Plane strain problem is currently prevalent in the loess engineering. However, this problem is still dealt with using conventional triaxial test method. This paper modifies triaxial apparatus of Xi’an University of technology and realizes the plane strain experiments, and analyzes comparatively the differences in plane strain experiments and conventional triaxial experiments under different moisture content and different confining pressure. The study shows：Moisture content is of greater impact on the strength of the soil than confining pressure under the two conditions;the soil strength of the plane strain condition is significantly greater than conventional triaxial condition under the same conditions. This shows that the approach to deal with the plane strain problem was conservative in the past. The research may play a guiding role in the construction. |
