双层卸荷板肋式悬臂挡土墙设计

Design of cantilever retaining wall containing costal type and double unloading platforms

依据首届全国岩土工程竞赛要求,设计出包括纵向肋柱,双层卸荷板和仰斜式墙面三方面组合创新的双层卸荷板肋式悬臂挡土墙。通过分层填筑的方式建造挡土墙模型,以获得逐级加载条件下挡土墙的水平位移与荷载值的变化规律。

According to the competition requirements of geotechnical Engineering,new type retaining wall,named cantilever retaining wall containing costal type and double unloading platforms,was designed including longitudinal stiffened pillars,double unloading platforms and oblique wall.Retaining wall model was built in the form of layered filling,therefore,the change rules are obtained by the curves between horizontal displacement of retaining wall and loads in the process of loading by step.
