| 摘 要： | 以十漫高速公路高边坡多级挡土墙为研究对象，在高达67m的填方路段进行墙背土压力试验研究，探索墙背土压力分布规律。在挡土墙墙背上按照一定间距安置了多个土压力测试仪，进行208d的定期测试。结果表明：随着填土高度的增长，墙背土压力经历快速增长、短期的平稳和缓慢增长阶段，两者最初近似成线性关系，之后表现为明显的非线性。 |

| Abstract: | Experimental study on soil pressure distribution laws of multistage retaining wall is conducted at high fill section of 67 meters during the construction of Shiman Highway. Periodic observation is carried out for 208 days after a number of soil pressure testers are placed at the back of multistage retaining wall in accordance with spacing. The results indicate that： soil pressure behind the retaining wall experiences stages of rapid growth, short-term stability and slow growth; the relation between soil pressure and depth of fill is approximately linear at the beginning, and turns to non-linear later. |
