［摘要］對于帶地下室或裙房的高層建筑，抗浮設(shè)計是重要的?，F(xiàn)常用抗浮錨桿設(shè)計方法不能考慮錨桿受力的不均勻性。建立包含錨桿、基礎(chǔ)和上部結(jié)構(gòu)的整體有限元模型來進(jìn)行抗浮計算，整體抗浮計算結(jié)果表明，錨桿和底板的變形和受力是相互影響的；錨桿的實際承載力可能明顯大于按現(xiàn)常用方法設(shè)計的結(jié)果，而實際所需錨桿數(shù)量少于按現(xiàn)常用方法設(shè)計的結(jié)果。給出了整體模型中錨桿剛度的計算方法。

Abstract: For high-rise building with basement or podium, anti-floating design is important. Current design method of anti-floating anchor takes no account of stress nonuniformity of the anchor. An integral FEM model, which contains the anchors, foundation and the upper structure, was established to carry out anti-floating calculation. The integral anti-floating calculation results show that the deformation and stress of the anchors and the base slab influence each other. Compared with the design result with the current method, the actual bearing capacity of the anchors are larger. Numbers of needed anchors in actual is less than that from results with current method. The calculation method to calculate the anchor stiffness in the integral model was provided.
Keywords: Anti-floating; integral calculation method; anchor; anchor stiffness; foundation
