摘　　要：根据目前的试验研究,本文提出了一种桶形基础的水平承载力的计算模型,并据此模型推导桶形基础水平承载力计算公式。该模型考虑了当桶体发生转动时土体对桶体的剪切作用。水平承载力公式按照三维空间问题进行推导,形式简单,计算方便,有较强的实用价值。最后根据试验结果验证了该公式的合理性。On the basis of experimentation research of the bucket foundation, this paper brings forward acalculation model about the horizontal bearing capacity. The model takes the shearing effect of the soil on the bucketfoundation into account. A simple calculation formula of the horizontal bearing capacity is deduced according to the model. The formula is educed as a 3D problem and it is simple and convenient to use. At last the calculation conclusion is tested byan experimental conclusion.
