超大型地下停车场的结构抗浮设计

Structural Anti-Floating Design of Super Large Underground Parking Lot

以广州地铁首座超大型地下全埋式停车场——石湖停车场为例,根据工程地质和水文条件,分析了地库结构抗浮设计的重难点,继而通过方案比选,采取了有针对性的结构抗浮设计措施,如适当增加结构自重,将抗拔桩集中设置在相应地段等,从而有效地保证了地下结构的整体抗浮能力。

Taking the Shihu parking lot,the first super-large underground fully buried parking lot in Guangzhou Metro as an example,according to the engineering geological and hydrological conditions,the key and difficult points in the anti-floating design of underground parking lot structure are analyzed,and then through the scheme comparison and selection,the corresponding structural anti-floating design measures are taken,such as increasing the structural selfweight appropriately,set the anti-uplifting piles in the corresponding area and so on,so as to effectively guaranteeing the overall anti-floating ability of the underground structure.
