建筑物基础抗浮设防水位之我见

View on Water Level for Prevention of Up-floating

根据阿基米德原理,当建筑物基底处地下水水头压力大于基底荷载时,建筑物将会发生上浮事故。为保证建筑物不发生上浮事故,设计前必须确定保障建筑物安全的地下水水位高程,该高程一般被称为建筑物抗浮设防水位。以实例形式对当前几种确定建筑物抗浮设防水位的不同观点进行了分析讨论,并提出了自己的看法,可供确定建筑物抗浮设防水位设计工作的参考。

Based on the Archimedean Principle, building basement floating accident occurs when the groundwater head pressure beyond the foundation pressure. In order to insure the safe of the building, the safe groundwater level height, referred as water level for prevention of up-floating in general, must be confirmed before the design stage. The current different viewpoints on the determination of water level for prevention of up-floating are verified by the examples,and suggestion which may be a reference to the determination of water level for prevention of up-floating is put forward.
