钢塑复合拉筋带加筋土挡土墙设计

Design of Overflow Retaining Wall Anchored by Steel-plastics Reinforcement

深圳某工程应用钢塑复合拉筋带加筋土构筑挡土墙 ,形成溢流直立坡 ,单级直立高度 18m ,较原块石混凝土溢流坝方案节约投资 70 % ,同时又获得了形成单级高瀑布的景观要求。介绍了钢塑复合拉筋带加筋土挡土墙的设计及施工工艺流程 ,并以工程实例比较了其经济性。

The retaining wall is 18 m high and is composed of vertical slab, footing block and overflow cap. The vertical slab is anchored with the soil mass behind the wall by steel-plastics reinforcement, and thus the engineering cost of the retaining wall is saved about 70% than the rubble concrete gravity wall. The design and construction program are described, and an engineering example is given to show its economic effectiveness.
