摘要
通过工程实例，对既有建筑物地基基础因为产生不均匀沉降而进行高压注浆托换法加固的施工技术做简单介绍，阐述利用人工挖孔高压注浆桩对既有建筑物地基基础进行固结稳定和托换法的加固施工工艺。
Based on some engineering cases, a brief introduction of strengthening existing building foundations by high-pressure grouting & underpinning construction method to solve the non-uniform settlement problems is described in this paper. Here the procedure and keys to using high-pressure grouting piles to reinforce and support existing buildings are mainly discussed.
