根据裙房作用于基底的压力不小于或者小于基底水浮力两种情况，推导和分析了基底水浮力对主裙楼一体结构地基承载力验算的影响。计算结果显示，基底水浮力对地基承载力验算有较大影响。第1种情况下，地下水位上升对地基承载力验算一般为不利因素。第2种情况下，基础持力层为粘性土、粉土时，水位上升对地基承载力验算一般为有利因素；基础持力层为砂土、碎石时，水位上升对地基承载力验算一般为不利因素。本文建议进行地基承载力验算时应考虑地下水的影响，最终取值宜综合考虑。

According to the two cases that the pressure of podium acting on the basement is not less than or less than the water buoyancy of the basement, the influence of the water buoyancy of the basement on the checking calculation of the bearing capacity of the foundation of the integrated structure of the main podium is deduced and analyzed. The calculation results show that the base water buoyancy has a great influence on the foundation bearing capacity checking. In the first case, the rise of groundwater level is generally a disadvantage to the calculation of bearing capacity of foundation. In the second case, when the foundation bearing layer is clayey soil and silt, the rise of water level is generally favorable for the calculation of foundation bearing capacity; when the foundation bearing layer is sandy soil and gravel, the rise of water level is generally unfavorable for the calculation of foundation bearing capacity. This paper suggests that the influence of groundwater should be considered when checking the bearing capacity of foundation, and the final value should be considered comprehensively.<br>
