[摘要] 上海地区在本次修编1999版上海市《地基基础设计规范》过程中，对于浅层褐黄色粘性土和粉性土进行了11个场地38组平板载荷试验，试验结果表明上海地区天然地基极限承载力是实际存在的，也是基本稳定的。通过将试验结果与Skempton公式和Hansen公式计算极限承载力的结果进行比较，认为Hansen公式更适合上海土层特性，但将其用于上海地区天然地基极限承载力计算时必须进行系统性的修正。

Abstract: As a preparation for the revising of Shanghai Foundation Design Code,  a series of loading test of natural foundation was camed out on the clay or silt, which included 38 plate tests in 11 fields. The test results showed the ultimate bearing capacity of natural foundation in Shanghai is stable.  Based on these testing data, it was considered better to use Hansen formula for calculating the ultimate bearing capacity in Shanghai area compared with Skempton formula. But modification must be taken into consideration in the calculation with Hansen formula.
