摘要
针对深水大直径超长群桩基础存在的技术难题,探讨了桩底注浆提高桩端承载力的机理,详细地介绍了桩底注浆工艺、桩底注浆材料及施工过程,对桩底注浆效果进行了分析研究,以促进桩底后注浆技术的应用。
In light of the technical difficulties existed in deepwater large-diameter super-long group piles foundation, the article discusses the mechanism of improving the pile end＇s bearing capacity by pile bottom grouting, introduces the technology, materials and construction process of pile bottom grouting, and analyzes its effect, in order to promote the application of pile bottom post-grouting technology.
