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。
Shanghai Region During the revision of 1999 edition of the “Foundation Design Code for Foundation” in Shanghai Municipality, 38 sets of flat-panel load tests were conducted on shallow brownish cohesive soil and silt soil at 11 sites. The results show that the natural foundation limit Bearing capacity is real, but also basically stable. By comparing the test results with the results of Skempton formula and Hansen formula to calculate the ultimate bearing capacity, Hansen’s formula is considered to be more suitable for the soil properties of Shanghai. However, it must be systematically revised when applied to the calculation of ultimate bearing capacity of natural foundations in Shanghai.
