摘要
文章简要介绍了国内灌注桩后压浆法的应用情况,分析了灌注桩桩侧后压浆和桩端后压浆的增强机理,并结合工程实例介绍了后压浆质量控制要点。实践证明灌注桩后压浆技术能显著提高单桩极限承载能力,并能有效控制桩顶沉降量。
The article briefs the application of post pressure grouting to bored pile by describing the strengthening mechanism of pressure grouting to the resistance at pile side and pile end and by presenting quality-control essentials of post pressure grouting. Engineering practice indicates that post pressure grouting can marginally increase the ultimate bearing capacity and effectively lessen settlement of the bored pile.
