简述了目前地下结构抗浮设计存在的一些问题，分析了抗浮锚杆在结构设计中各种布置方法的优缺点，并对目前最常见的两种锚杆布置方式进行了力学对比计算，提出了较为合理的锚杆布置方式。%This thesis states some problems about anti-float design of subterranean structures recently and analyses the merits and demerits of arrange methods of anti-float anchors in structure designs. In addition, it carries out mechanics contrast calculation toward two most common arrange methods of anti-float anchors and presents relatively reasonable arrange methods of anti-float anchors.
