摘要
广州塔平台层采用了大柱跨双重井式楼盖,为景观广场及重型消防车行走区域。重点针对梁、板、柱构件的消防车等效荷载取值进行了探讨,对包含平台层的整体模型及平台层消防车道的铺装进行了描述。针对大体量混凝土结构采取了设置后浇带、采用预应力梁、加强楼板配筋及加强施工养护等设计及施工措施,采用设计及施工措施后,平台层未发现裂缝。
The podium level of Canton Tower, as the landscape square and heavy fire truck covering field, adopts large column-span structure with double waffle slabs. The equivalent loads of fire truck of beam, slab and column members were discussed. The overall model including the podium level was described as well as the pavement of the fire truck road on the podium level.
