| 摘 要： | 本文首先简要地讨论了碎石桩复合地基可能的破坏模式，随后系统地分析了三十几组复合地基的实测数据，探讨了这种加固处理技术可能达到的效果。通过对桩土应力比、面积置换率以及天然地基压缩模量对复合地基承载力的提高和沉降折减系数的影响的讨论，指出了这些参数在设计取值时所需注意的问题。

| Abstract: | A number of field test data of stone column composite grounds are systematically analoged. From a practical point of view, the effects of stress concentration ratio, the replacement ratio and the soil moduli on the bearing capacity enhancement and settlement reduction of composite grounds are discussed. The limits of ground improvement. by stone columns are proposed. |

| Keywords: | Composite ground Stone column Bearing capacity enhancement coefficient Settlement reduction coefficient. |
