冲击压实在高填方施工中的应用

Application of Impact Compaction in High-filled Embankment Construction

为了提高高填方压实的质量,减少工后病害的发生,分析了冲击压实的原理,采用对比方法分析了高填方的施工现状,认为高填方高差大、填料复杂、施工条件不易控制,普通压实方法不易满足压实质量要求。冲击压实应用于高填方施工的结果表明:冲击压实具有压实影响深度大、生产率高、施工成本低等特点,用于高填方施工具有明显的优势。

In order to improve quality of high-filled embankment and reduce disease of compaction, the paper analyzes the theory of impact compaction. Compared with other compaction methods, high-filled embankment has altitude differences, different filling and its construct conditions are difficult to control. The ordi- nary compaction methods are put forward to ensure the compaction quality. The result shows that impact compaction has obvious superiority for high-filled embankment such as high compaction depth and productivity and low cost.
