对悬臂式钢筋混凝土挡土墙与卸荷式钢筋混凝土挡土墙受力分析比较，可以看出同样高度的卸荷式挡墙较悬臂式挡墙在挡墙墙壁根部所受弯矩要小，这样可以减小挡墙墙壁的壁厚及配筋，同时也可以减小倾覆力矩，即可以减小挡墙底板宽度，本文还对确定卸荷式挡墙悬挑板的位置进行了分析。 Comparing and analyzing the force of the cantilever reinforced concrete retaining wall and the unloading reinforced concrete retaining wall, we can see that the unloading retaining wall of the same height is smaller than the bending moment of the cantilever retaining wall at the wall of the retaining wall. In this way, the wall thickness and reinforcement of the retaining wall can be reduced. At the same time, the overturning moment can also be reduced, ie, the width of the bottom wall of the retaining wall can be reduced. The position of the unloading retaining wall cantilever plate is also analyzed.
