大直径桩端后注浆灌注桩在某工程中的应用

Application of Large-diameter Pile-end Post-injection Grouting Pile in a Engineering

文中结合郑州地区某工程实例,对比分析该工程大直径桩端后注浆灌注桩的静载试验结果,试验数据表明,桩端后注浆技术能有效提高单桩竖向承载力,进一步节约成本,可为该地区同类项目的桩基础设计及施工提供一定参考。

Based on an engineering example in Zhengzhou,this paper compraes and analyzes the static load test results of large-diamete rpile end post-grouting pile,and the test data show that the post-plei end grouting technology can effectively improve the vertica bl earing capacity of monopile and further save costs,which can provide certain reference value for pile foundation design and construction of similar projects in this area.
