| 中文摘要: |
| 水泥土桩复合地基承载力的确定,目前常用的方法是现场载荷试验,并被公认为是比较可靠的方法。结合工程实测资料,讨论了用该法确定水泥土桩复合地基承载力的取值问题,提出用相对变形 S/b 的取值是合理的。同时通过一定数量的水泥土单桩静载荷试验、单桩复合地基载荷试验和多桩复合地基载荷试验对比分析,说明用一组桩和桩间土所组成的单元体进行承载力试验,更接近实际复合地基的受力性状和承载机理。 |

| Atpresent dead load test is a general way of ascertaining bearing capacity of composite ground of ccmcnt soil pile and it is rcgardcd as a reliablc method.With certain projects information as example,this paper discusses the method of getting the value of bearing capacity,thinks it reasonable to get limited value of relative deformation S/b.By comparison analysis of some dead load experiments on single stake,composite ground of cement soil single stake and multi-stake,the authors thinks bearing capacity experiment on element made up stake and around soil is good agreement with actual bearing mechanism of composite ground. |
