| 摘 要： | 对深圳湾填海区强夯块石墩道路软基处理工程的沉降资料进行分析，指出强夯块石墩复合地基在荷载作用下的沉降由3部分组成．强夯引起的淤泥固结沉降及块百垫层荷重作用下复合地基的剩余沉降占总沉降相当大的比例．并由实测资料推算了最终沉降量，评价了强夯块百墩加固软基的工程效果。

| Abstract: | The observation data of composite foundation treated with dynamic compacted stone piers are analyzed, and the conclusion make out that the settlement of composite foundation with heavily rammed stone piers can be divided intothree parts. Consolidation settlement of soft soil induced by dynamic compaction and the residual settlement under loading of rubble bedding,which takes a large proportion of total settlements. The ultimate settlement is calculated on the basis of monitoring data and the reinforcement effect of dynamic compacted stone piers is evaluated. |
