摘要
随着桩基施工技术的不断发展,后注浆技术在我国岩土工程建设中应用越来越广泛。论述了钻孔灌注桩的后注浆工艺,同时结合工程实例,分析了该技术对提高单桩竖向承载力,改善桩基承载工作特性的效果,以供参考。
With the continuous development of pile foundation construction technology,post-grouting technology is increasingly used in China’s geotechnical construction.This paper discusses the post-grouting process of bored cast-in-situ piles,and combines engineering examples to analyze the effect of this technology on improving the vertical bearing capacity of a single pile and improving the bearing performance of the pile foundation for reference.
