摘　　要：近年来,既有建筑地基发生不均匀沉降的现象越来越多,无疑增加了人们对建筑工程质量的担忧,因此,建筑施工单位有必要科学分析既有建筑地基产生不均匀沉降现象的原因,有针对性地选择相应的地基加固方法,以提升既有建筑地基的稳定性,推动建筑行业长久发展。针对高压旋喷桩法加固工程在既有建筑地基上的应用展开研究。In recent years,there have been more and more uneven settlement of existing building foundations,which undoubtedly increased people’s concerns about the quality of construction projects. Therefore,it is necessary for building construction units to scientifically analyze the causes of uneven settlement of existing building foundations,and to select corresponding foundation reinforcement methods in order to improve the stability of existing building foundations and promote the long-term development of the construction industry. This article studies the application of the high-pressure rotary jet pile method to the reinforcement of existing building foundations.
