浅析强夯法在湿陷性路基工程中的应用

Application of Dynamic Compaction Method in Collapsible Subgrade Engineering

针对安达煤矿湿陷性进场道路,为消除湿陷性路基的不均匀沉降,使道路承载能力满足运输相关要求,采用强夯法加固路基。通过对强夯设备选择和夯击参数的分析,制定了从施工准备、施工事前和过程控制,到具体施工步骤的现场强夯施工技术措施,基于工程应用效果总结了强夯法的优缺点。强夯法的应用对降低投资起到了积极作用。

Aiming at the collapsible approach road in Anda Coal Mine,in order to eliminate the uneven settlement of collapsible subgrade and make the road bearing capacity meet the transportation requirements,the dynamic compaction method was adopted to reinforce the subgrade.Through the analysis of the selection of dynamic compaction equipment and the tamping strike parameter,this paper worked out the technical measures of dynamic compaction construction on site from construction preparation,pre-construction and process control to concrete construction steps.Finally,this paper summarized the advantages and disadvantages of dynamic compaction method in the engineering application effect.The application of dynamic compaction method has played a positive role in reducing investment.
