| 摘 要： | 在高填方工程中,压实质量是工程成败的关键因素。强夯法所具有的优点,使其在许多地基处理工程中都有广泛的应用。某山区高填方工程,根据工程的实际需要,采用强夯法对山体爆破块碎石填料进行密实处理。为此,开展现场试验研究。首先对爆破的块碎石填料进行了颗粒分析试验和压实试验,分析其可填性和压实特征。按照试验参数和工序,分别进行了2000kNm、3000kNm单点夯试验;同时夯后进行了密实度试验、颗粒分析试验。由此,确定了合理的强夯施工参数。最后根据面层载荷试验的检测,以此确定的施工参数在该工程取得了良好的处理效果。

| Abstract: | The quality of compaction is crucial to high-filling. Dynamic compaction is a most widely used method for ground treatment. In the paper, experimental test for broken stone treatment by dynamic compaction is studied. Firstly, the properties of the filling of broken stones are analyzed. Secondly, the dynamic compaction test, the dry density test, and the particle-size distribution test are tried out. Thus, the reasonable working parameters and working techniques are defined. Lastly, based on the load-settlement test, the result of the stabilization is well acquired in according with work parameters. |
