摘要
对某工点桩基在不同工况下的静载试验数据进行分析研究,结果表明,采用后压浆技术后,桩顶沉降速度减缓,沉降量减少,桩侧阻力、端阻力均大幅度提高,桩基承载力提高45%以上;采用后压浆技术更能确保桩基承载力。
In this paper, the static load test data of the pile foundations under different load cases at a construction site are analyzed and studied. The results of the analysis and study show that after application of the post-grouting technique to the foundations, the pile top settlement rate slows down and the settlement amount decreases. The pile side and tip resistance greatly increases, the bearing capacity of the foundations increases more than 45% and the application of the post grouting technique can better ensure the bearing capacity of the foundations.
