摘要
本文结合工程实例,并根据工程地质情况,详细分析阐述了钻孔灌注桩承载力和桩端桩侧后注浆施工技术及质量控制措施。试验结果表明,一般施工的钻孔灌注桩承载力达不到设计要求,必须对桩端桩侧进行后注浆处理,处理后单桩竖向承载力有大幅度提高,且经济性能较好。
This paper combined with engineering example and based on engineering geological conditions, bearing capacity of bored pile, construction technology of pile-end and pile-side post-grouting, and measure of quality control were elaborated and analyzed. The result show that general bearing capacity of bored pile of can not meet the design requirements, accordingly, pile-end and pile-side must be treated by post-grouting. After treatment, vertical bearing capacity of single pile had greatly improved, and economy was well.
