抗浮锚杆在岭澳核电站油水分离器厂房FS工程中的应用

Application of anti-floating anchor rod for oil-water separating workshop in Lingao Nuclear Power Station

岭澳核电站油水分离器厂房FS为深11 7 m的海边地下结构, 周围地下水位较高且与海水相通, 故其抗浮稳定分析与抗浮措施选择是设计的控制因素。通过介绍岭澳核电站FS厂房抗浮锚杆的设计, 探讨了带锚杆底板的内力计算模型。工程实践表明: 在地质条件允许时, 打锚杆是解决地下结构抗浮问题的简单、有效措施。

The oil-water separating workshop (FS) in Lingao Nuclear Power Station is an 11.7 m-deep underground structure near the sea.The water lever around FS is high and in connection with the sea water,so the anti-floating stability analysis and the selection of anti-floating method are the critical factors in design.The design of the anti-floating anchor rod for FS is introduced and the calculation model of the base with the anti-floating anchor rod is discussed.The engineering practice shows that the anti-floating anchor rod is a simple and valid method for solving the floating of underground structures when the geological conditions are adaptable.
