摘 要: A series of centrifuge model test of "Compacted Bulb Foundation Method" was carried out to investigate the effect of tamping conditions, such as ram mass, ram base area and number of blows, and foundation base area on characteristics of its bearing capacity. Main conclusions are as follows: 1) ultimate bearing capacity and coefficient of subgrade reaction of compacted bulb was hundred times or more and ten times larger than untamped ground, respectively, 2) its bearing capacity was dependent on the ram mass per unit base area, 3) compacted bulb tamped by a ram having larger base area relative to loading area had lager bearing capacity.

对“压实球形基础法”进行了系列离心模型试验,以研究压实条件(如压重质量、压重底面积和击打次数)以及基础底面积对其承载能力特性的影响。主要结论如下:1)压实球形基础的极限承载力和路基反力系数分别比未压实的地面高出数百倍和十倍以上; 2)其承载能力取决于单位底面积的压重质量; 3)用底面积相对于加载面积较大的压重进行压实的球形基础具有更大的承载能力。
