卸荷式与悬壁式挡土墙受力分析与比较

LOADING ANALYSIS AND COMPARISON OF THE UNLOADING TYPE AND CANTILEVER TYPE RETAINING WALL

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。

From the Ioading analysis and cornparison of the unloading type and cantilever type reinforced concrete retaining wall,it can be seen that the unloading type retaining wall bears less bending moment at the root part of the wall than that of the cantilever type with equal height. In this way,the wall thickness and the steel reinforcement can be reduced. At the same time,the overturning moment can be reduced, that is the width of the base plate of the wall can be minified. This paper also analyzes the fixation of the cantileve slab of the unloading type retaining wall.
