悬臂式钢筋混凝土挡土墙加设钢塑土工格栅加筋带的探讨

Discussion of Installing Steel-Plastic Geogrid Reinforced Belt on Cantilever Reinforced Concrete Retaining Wall

本文提出在悬臂式钢筋混凝土挡土墙背面填土区内水平分层铺设钢塑土工格栅加筋带,并与立壁铰接。右面部分的锚固力作用在悬臂式挡土墙的立壁上,形成与主动土压力方向相反的力,对改善悬臂式钢筋混凝土挡土墙的受力情况有着至关重要的作用。

Plastic geogrid reinforced belts are laid horizontally in soil-filling area on the back of cantilever reinforced concrete retaining wall layer by layer. The reinforced belts are hinged with vertical walls. Anchoring force in the right part is acted on the vertical wall of the cantilever retaining wall, thereby forming force opposite to active earth pressure direction. It is critical for improving the force condition of cantilever reinforced concrete retaining wall.
