摘　　要：随着河北省经济建设的高速发展,基础设施建设的规模在不断扩大。河北省地区幅员辽阔,地质条件也是很复杂,在进行施工建设的时候会遇到很多软地基的情况需要处理。墩式碎石注浆桩可以有效把碎石桩法和注浆法结合在一起对地基进行加固,墩式碎石注浆桩法是新型的软地基处理技术。对墩式碎石注浆桩技术进行了简单的介绍,对墩式碎石注浆桩法在地基加固中的施工工艺进行了研究,结合河北省地区地质条件的实际情况,对墩式碎石注浆桩技术在地基加固中的应用进行了研究。With the rapid development of Hebei＇s economic construction, the scale of infrastructure construction is expanding. Hebei province has a vast territory and geological conditions are very complex.In the course of construction, many soft foundation conditions will be encountered. The pier type gravel grouting pile can effectively combine the gravel pile method and the grouting method to reinforce the foundation. The pier type gravel grouting pile method is a new soft foundation treatment technology. In this paper, the technology of pier type gravel grouting pile is briefly introduced. The construction technology of pier type gravel grouting pile in foundation reinforcement is studied. The application of pier type gravel grouting pile technology in foundation reinforcement is studied in combination with the actual situation of geological conditions in Hebei province.
