设备地坑的抗浮稳定问题

STABILIZATION PROBLEM OF FOUNDATION BED FOR INSTALLATION OF EQUIPMENT——FLOATING RESISTANCE

本文应用实例论述处在高地下水位地段的设备地坑,由于地下水的作用,要进行抗浮验算。在这种情况下,抗浮条件是控制结构设计的主要因素。笔者根据自己的工作实践,提出几项抗浮构造措施,供结合具体情况选用,以保证结构安全。

The author of the paper by means of concrete examples demonstrates that the floating resistance of the foundation bed in places with high groundwater level should be tested and calculated. In such cases, floating resistance is the main factor to control the structure design. According to his own experience the author gives some suggestions of structure design for resistance to floating, which can be selected and used in different concrete conditions to ensure safty of the structure.
