| 摘 要： | 水泥土粉喷桩和软土组成复合地基,共同承担上部荷载。进行了粉喷桩复合地基的特性研究。在静载荷试验基础上,分别对复合地基的承载力、桩土应力比以及桩间土所承担的总上部荷载的百分比三个方面进行了详细的分析和研究,得到了粉喷桩的桩身强度上部较大而下部较小等结论,旨在为其进一步研究和工程应用提供参考。

| Abstract: | Cement-soil DJM piles and soft soil may consist of composite foundation withstanding external loads. The characteristics of such composite foundation of DJM pile were studied in the paper. Based on static loading tests, bearing capacity of the composite foundation and stress ratios of pile to soil, as well as the per?cent total load born by soil, were analyzed in details. Conclusions from the analysis included that the strength of DJM pile shaft is higher at upper part and lower at the bottom, which provide reference for engineering ap?plications and further study. |
