| 摘 要： | 采用在水泥土桩单桩复合地基载荷试验中设置不同厚度褥垫层的方法 ,将其试验结果与无褥垫层的单桩载荷试验资料进行对比分析 ,探讨了褥垫层作用下桩土应力比的分布规律 ,并得到了桩土应力比与褥垫层厚度的变化规律。该研究为褥垫层合理厚度的设置及复合地基的优化设计提供了依据。

| Abstract: | Several loading tests of single pile for the cement\|soil pile composite foundations are conducted with the cushions of different thickness. The experimental data from the tests with cushions are compared to the data from loading tests without any cushions.The influence of the thickness of the cushions to the pile\|soil stress ration is studied, which could provide a theoretical base for the selection of the thickness of the cushion and the optional design for composite foundation. |

| Keywords: | composite foundation loading test variable thickness cushion pile\|soil stress ration |
