| 摘 要： | 对铁路路堤式加筋土挡墙的墙面板水平土压力、墙后土体垂直土压力及加筋材料变形进行了现场原位试验,分析了加筋土挡墙面板水平土压力沿墙高的变化及分布规律、墙后土体垂直土压力变化及加筋材料的变形随填高及时间的变化规律。路堤式加筋土挡墙的面板水平土压力沿墙高呈曲线型分布,同一水平面同一层拉筋的不同位置垂直土压力不一致,实测垂直土压力与理论垂直土压力的比值随距面板的距离增大而线性增大,并得出了路堤式加筋土挡墙的破裂面。 |

| Abstract: | This paper describes the in-situ measurement of lateral earth pressure,vertical earth pressure and geobar deformation of a geobarreinforced retaining wall for a railway embankment.Distribution and variation of the lateral earth pressure,the vertical earth pressure and the geobar deformation with filling height and time are analyzed.The lateral earth pressure is observed as nonlinearly distributed,and at a given level the vertical earth pressure is non-uniformly distributed along the geobar.The ratio of the theoretical and experimental vertical earth pressures increases linearly with the distance from the face.The failure plane for the geobar embankment retaining wall is provided. |
| Keywords: | railway reinforced earth-embankment wall earth pressure deformation experimental study |
