粉喷桩技术在高速公路软基处理中的应用

Application of the Cement Powder Spraying Pile Technique in Soft Foundation Treatment on Express Roads

粉喷桩作为软基处理的有效手段广泛应用于工程领域,本文结合高速公路软基施工实践,分析了粉喷桩的加固机理,介绍了粉喷桩的施工工艺流程、质量控制措施,并对粉喷桩软基处理效果进行了分析。应用结果表明,粉喷桩在处理高速公路软基中的可行性和有效性。

As soft foundation treatment means,the cement powder spraying piles are widely used in engineer-ing field.In the paper,combining with the practice of soft foundation construction on express roads,it analysed the reinforcement mechanism of the cement powder spraying pile,introducing its construction process and quality con-trol measure,and discussing the effect of soft foundation treatment on express roads.The application shows that the cement powder spraying pile technique is feasibility and validity to treat with soft fountation on express roads.
