| 摘 要： | 通过对方形和圆形基础地基极限承载力的经验公式、理论解、静载荷试验结果进行对比分析，得到下列结论：对于砂性土，经验公式和理论解的计算结果明显偏小；对于粘性土，Vesic经验公式的计算结果更接近静载荷试验结果；李伟理论解适合于软粘性土，而周中理论解适合于高强度的粘性土。

| Abstract: | Through analyzing ultimate bearing capacity of square and circular foundations using three equations and two theoretical solutions, it is shown shows that (a) result of equation and theoretical solution is obviously less than the data of load test for sand, (b) result of Vesic’s equation is closer to the data of load test for clayey soil; (c) result of Li’s solution is proper for soft clayed soil, but Zhou’s solution is fit for high strength clayed soil. |

| Keywords: | ultimate bearing capacity equation theoretical solution field plate load test |
