摘要
通过对某机场强夯试验加固效果的分析 ,认为在上海软土地区设置强夯垫层并对沟河浜进行清淤填土 ,强夯后能形成厚达 7m较均匀密实的硬壳层 ,表层地基土由特低～低强度类型变为高强度类型 ,达到减少施工后地基残余沉降和差异沉降的作用。
This paper analyses the consolidation effect of dynamic compaction test for one airport runway construction. It's concluded that homogeneous hard layer of 7m thick can be formed by dynamic compaction in Shanghai region after underlying layer is piled up and the river is cleared away silt, and the strengthen of surface foundation soil is turned high from lowest～low type, aiming at reducing residual settlement and unequal settlement after construction.
