摘　　要：《高层建筑岩土工程勘察规程》(JGJ72—2004)指出,场地抗浮设防水位可采用实测最高水位,但未指出在多层地下水的情况下,可采用基础底板所在层的最高水位作为抗浮设防水位。对此问题进行探讨。According to Specification for Geotechnical Investigation of Tall Buidings（JGJ 72--2004）, the water level for prevention of up-floating should adopt the highest water level determined during investigation construction. But this specification doesn＇ t suit the condition of multi-level grounduater.Therefore, the determination method of water level for prevention of up-floating under the condition of multi-level groundwater is discussed, and the condusion is：the water level for provention of up-floating under the condition of multi-level groundwater should adopt the highest water level of the stratum sat by foundation.

关 键 词：最高水位 多层地下水 抗浮设防水位 高层建筑 基础底板
