摘　　要：经公式推导,将JTS 147-1—2010《港口工程地基规范》中关于均质土地基(φ>0)、均布边载上的重力式码头地基承载力计算的区间总和求解方法简化,得到公式求解法。利用地基极限承载能力曲线与实际荷载设计值曲线推导出二者交点b交=0.5Be。在结构算例中应用上述2种方法进行地基承载力计算,得到相近的结果,验证了公式求解法。According to Code for Soil Foundation of Port Engineering （JTS 147-1--2010）, we obtain a formula for calculating the foundation＇s bearing capacity of gravity wharf based on homogeneous soil（φ〉0）and side loading, which is calculated originally by dividing the foundation width into many intervals and summing the ultimate bearing capacity. The intersection point b交=0.5Be is derived by the ultimate bearing capacity curve and the design load curve. The formula is verified by the two methods in the same example.
