| 摘 要： | 从地基沉降和承载力两个方面分析了素混凝土桩复合地基的作用机理，在沉降计算中将地基加固区沉降量和下卧层沉降量均按照分层总和法考虑，并结合石家庄某实际工程，从承载力和地基沉降量两个方面对索混凝土桩复合地基的作用机理进行分析验证。结果表明素混凝土桩复合地基可以大幅度提高基础承载力，并且地基沉降较小，该研究对实际的地基处理具有一定指导意义。

| Abstract: | The working mechanism of the plain concrete pile composite foundation is analyzed from two aspects in the paper：foundation settlement and loading capacity. The layer-wise summation method is adopted to analyze the foundation deformation in the reinforced area and under the reinforced area. Besides, the working mechanism of the plain concrete pile composite foundation is tested with an actual project in Shijiazhuang. The test results show that the plain concrete pile composite foundation can greatly increase the loading capacity of the foundation and decrease the settlement. The research may serve as a useful reference for foundation treatment. |
