| 摘要: |
| 加筋挡土墙的设计方法主要依据是Ｒａｎｋｉｎｅ的主动土压力理论。本文用极限分析的方法证明，常规的设计方法仅是真解的一个下限解，且具有一定的保守性。而本文的上限解则与离心模型的试验结果较为一致。 |

| Abstract: |
| The design methods of the reinforced retaining wall are mainly based on the Rankine's earth pressure theory. In this paper, the apparent effective cohesion theory is used in limit analysis directly and the upper bound solutions of this kind of structure are obtained.Centrifuge test results indicate that the current design method gives conservative result while the upper bound solution has a good agreement with the test. |
