后注浆灌注桩的地基加固机理及施工

摘要

The paper introduces the foundation consolidation mechanism and technical features of the post-grouting bored piles,surveys the post-grouting construction craft,and proves by the engineering practice that the technique has higher application and its construction quality is easily controlled with better social and economic benefits,so it has broader application and extension in China.%介绍了灌注桩后注浆的地基加固机理及其技术特性，概述了桩底后注浆技术的施工工艺，并通过工程实践证明：该技术实用性强，施工质量易控制，具有显著的经济和社会效益，且在我国有极大的应用与推广前景。
