卸荷式与悬臂式挡土墙受力分析比较

Comparison of force balance analysis between relieving and cantilever retaining wall

通过对悬臂式挡土墙与卸荷式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。

Through comparison of force balance analysis between cantilever and relieving retaining wall, it shows that, at the same height, relieving retaining wall suffers smaller bending moment at the lowest part of the wall than cantilever retaining wall. Using relieving wall can reduce the thickness and mixing reinforcement of retaining wall,and can reduce overtum mcment,i. e. the width of the base plate of retaining wall.
