碎石桩法加固软基在高速公路施工中的应用

The application of gravel compaction pile in soft soil foundation treatment of expressway

结合现场施工，分析了碎石桩的地基加固机理，介绍了碎石桩的施工工艺及工艺参数的确定方法，经过工程实践证明，碎石桩处理软弱地基是可行的。

Combined with on-site construction the working mechanism of gravel compaction pile in foundation reinforcement is analyzed. The construction technology as well as determination method of technological parameters of GC pile are introduced. Practice shows the application of gravel compaction pile in soft soil foundation treatment is practicable.
