强夯法施工在文安县城防洪圈工程中的应用

Application and Analysis about the Dynamic Compaction Construction in the Flood Prevention Circle of Wen＇an County Town

强夯法主要用于地基加固处理，在堤防工程中应用相对较少。为了检验强夯法施工在堤防加固工程中的处理效果，结合文安县城防洪圈工程北围堤加固处理措施实例，对强夯法施工方案和清除后再填筑处理方案在工程造价方面进行了对比分析，对强夯法施工原理、设计方案、施工步骤及注意事项进行了介绍，并对处理前后现场检测数据进行了对比分析，最后总结了此方法的优缺点和处理效果及影响范围，对检验时间和检验数量给出了相应的建议，以期为类似工程处理方法提供参考。

The dynamic compaction construction is mainly used in the area of foundation reinforcement, seldom in embankment engineering. In order to test the application effect of the dynamic compaction construction in the embankment reinforcement engineering, according to the reinforcement case of the flood prevention circle of Wen＇an county town, the engineering cost contrast analysis about the dynamic compaction construction and the filling after clearing is done, the introduction about the construction principle, design program, construction procedures and the needing attentions of the dynamic compaction construction is given and comparison between the test data before and after coping. The advantages and disadvantages of dynamic compaction construction, application effect and influence scope are summarized. Some advices about test time and test number are provided. This research result can be a reference to the similar projects
