高水位软土地区地下室抗浮设计的探讨

Discussion on Anti-Floating Design of Basement in the Area with High Water Level and Soft Soil

摘要: 根据沿海高水位软土地区特点，提出了合理确定抗浮设防水位的原则。对各种抗浮措施进行归纳，并提出其适用条件。给出了抗拔桩数量的计算公式，并针对钻孔灌注桩抗拔桩的配筋计算和裂缝控制提出了自己的观点。本文还对抗浮区桩基础包络设计提出具体设计建议。

Abstract: According to characteristics of the coastal area with high water level and soft soil, the principle of reasonable determining anti-floating fortification ground water level was put forward. A variety of anti-floating measures were summarized, and its applicable conditions were advanced. The formula that is used for calculating quantity of tension pile was given, and some personal views about reinforcement calculation and crack control were presented. In this paper, some detailed design suggestions on pile foundation enveloping design in the area of anti-floating were raised as well.
