摘要
结合上海地区某工程采用桩端后注浆灌注桩的实例,分析了该工程3组试桩的静载荷试验结果,试验结果表明,采用桩端后注浆技术后,单桩竖向承载力可提高70%,总桩数减少约30%,取得了较好的经济效益,对该地区同类项目的桩基设计和施工具有一定的参考意义。
This paper gives an example of post-grouting bored pile in Shanghai,there are three test piles in the project.The results of static load test show that the bearing capacity of pile is improved by 70% and the number of piles is reduced by 30%.The project achieves better economic benefits and the example is instructive for design and construction of similar piles.
