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。
The in-situ tests of the horizontal earth pressure on the wall, the vertical earth pressure behind the wall and the deformation of the stiffened material of the embankment reinforced earth retaining wall were conducted in situ. The variation and distribution of vertical earth pressure, the change of vertical earth pressure and the deformation of stiffened material with height and time. The horizontal soil pressure of the embankment reinforced earth retaining wall is curvilinear along the height of the wall. The vertical earth pressures at different positions of the same layer of the same horizontal slab are inconsistent. The ratio of the measured vertical earth pressure to the theoretical vertical earth pressure varies with the distance from the slab Increases linearly and increases, and concludes the rupture surface of embankment reinforced earth retaining wall.
