摘要
实践证明强夯是一种行之有效的地基处理方法。但在软土地区许多成功的实例不同于常规的强夯压密 ,它是在软土表部回填厚层粗碎屑物质 ,并经强夯形成一层“硬壳”,在工程荷载作用时起应力扩散和屏蔽作用。虽然软土地基本身的加固效果甚微 ,但场地承载力得到大幅度提高。
Dynamic compaction method (DCM) is a effecient ground treatment way. But in soft soil ground it's differ from uniyersal law. The backfill material such as crushed and weathered stone are formed a hard strutum in the top layer by DCM, that can diffuse the load. The bearing capacity has been enhanced, though the changes of soft soil's property are small.
