［摘要］地下室柱下獨基的受力及配筋如何考慮底板水浮力對其的影響，是困擾設(shè)計人員的一個難題。如何合理有效的布置錨桿，并在設(shè)計中準確地考慮其對獨基及底板的不利作用，是個很有意義的研究課題。本文以某實際工程為背景，對幾種常見的抗浮錨桿布置方式進行了比較分析，驗證了在幾種布置方式下，抗浮錨桿受力差異不大，較為均勻；底板及獨基受力分析結(jié)果表明，抗浮錨桿均勻布置于底板中間部位，避開基礎(chǔ)，能有效地減小基礎(chǔ)底部彎矩和配筋，且底板受力均勻，彎矩及配筋較??；并對獨基加底板這種基礎(chǔ)形式下，抗浮錨桿的布置方式給出了合理的建議。

Abstract: The stress states of the single-foundation under the column of the basement and how to consider the influence of bottom water buoyancy on the reinforcement is a difficult problem which troubles the structural engineer. Therefore, the research subject is of vital significance. It focuses on how to arrange the anchor bolts reasonably and effectively and making an accurate considering in design about the adverse effect of the anchors on single-foundation and the base plate .Based on the actual project, the arrangement methods of several common anti-floating anchors were compared and analyzed, which verified that although they were arranged differently, there is little difference on the stress states of anti-floating anchors. They all were uniform. In addition, the results of stress states analysis on the bottom board and the single foundation indicate that if the anti floating anchor is uniformly arranged on the bottom board with the foundation avoided, the bending moment and the reinforcement of the base bottom can be effectively reduced, and the stress states of the bottom board can be uniform, and the bending moment and the reinforcement can be small as well. Then, reasonable suggestions can be found on how to arrange anti-floating anchors in this basic form with single-foundation and bottom board.
Keywords: anti-floating anchor; foundation; base plate; base moment
