| 摘 要： | 冲击压实是一种新型的土体处理方法,它具有效率高、综合成本低等优点,其影响深度特别符合公路、场道土基对有效加固深度的要求。本文以某大型填方土基工程为例,介绍了冲击压实技术在填方土基中的应用。在对粉土填料性状分析试验的基础上进行冲压施工,同时进行了沉降观测、压实度试验、载荷试验、回弹模量试验,通过试验结果分析确定了合理的施工参数,并根据检测取得了良好的冲击压实效果。以此次试验确定的施工参数在该工程取得了良好的压密效果和经济效益。

| Abstract: | Impacting compaction is a new method to strengthen soil mass. This method has many advantages, such as high efficiency and low cost. The depth influence of impacting compaction on the foundation meets requirements of road and airfield construction. With the example of a large filled silt project, this paper discusses techniques of impacting compaction. Based on characterization of silt, the impacting compaction is made and its effectiveness is determined. At the same time, additional laboratory tests and field observation are conducted, including observation of settlement, compacting test, load - settlement test, and modulus of elasticity test. Constructed with the parameters determined by testing, the project has gained both a good compaction effect and an obvious economic benefit. |
