从地基土承载力的计算公式出发，对比分析了不同基础宽度、不同基础埋深、不同土性的地基土承载力受水位变化的影响，分析显示：地下水位在基础底板以下变化时，对地基土的承载力影响较小，地下水位上涨至基础底板以上时，承载力明显下降。%The goal of this paper is to comparative analysis the influence of the bearing capacity of the foundation soil by the change of water level in different width of foundation,depth of the subbasement and quality of the foundation soil which is based on the bearing capacity equation in code,the analyzation shows that there is little effect to the bearing capacity when water level changes under the baseplate,nevertheless,when the head of groundwater raise upon the baseboard,bearing capacity will decline significantly.
