强夯置换法在大察高速公路中的应用研究

Research on the Application of Dynamic Compaction Replacement Method in Dacha Highway

大察高速公路察尔汗盐湖段路基基底为软弱的粉土层,路基基底承载力极低,施工图纸中采用了砾石挤密桩、强夯置换等施工工艺并取得了较好的处理效果,这里着重介绍强夯置换的处理方法及质量控制。

In the construction of Charhan Salt Lake section of Dacha Highway, silt layer is used as the subgrade base. For the low bearing capacity of subgrade base, gravel compaction pile and dynamic compaction replacement methods are introduced in treating low bearing capacity of subgrade base, and obtained good effect. In this paper, the dynamic compaction replacement method is mainly introduced.
