新型预制混凝土面板锚碇式加筋挡土墙设计

通过在加筋挡土墙筋带末端设置锚碇块,提出了一种新型的预制混凝土面板锚碇式加筋挡土墙,并结合欧美规范提出车辆荷载撞击极限状况下的结构验算方法。将国内外规范进行对比,指出国内外加筋挡土墙规范的不同之处。实际工程应用表明,该新型预制混凝土面板锚碇式加筋挡土墙结构更优、用料更省,有广阔的应用前景。

Design of new-type precast reinforced concrete panel wall with anchor block

A new-type precast reinforced concrete retaining panel wall with anchor block is proposed by setting anchor blocks at the end of the reinforcement.Based on the Euro code and American standard,we give the safety checking method under the extreme event limit state of vehicular impact.Also,by comparing domestic codes and foreign codes,we point out the differences between them.The practical application shows that this new-type precast reinforced concrete retaining panel wall with anchor blocks is better in structure and more economical in the use of materials.This new-type retaining wall has a broad application prospect.
