摘　　要：介绍了上海市轨道交通4号线修复工程的施工方案及实施措施。修复工程分东侧、西侧、中部明挖段及隧道对接段、两侧隧道清理段进行实施。对超深地下连续墙施工、超深地下障碍物清理、超深双高压旋喷加固、超深承压水降水、连接段冻结暗挖施工等进行叙述。修复工程的完成,提升了国内软土地下工程的施工技术水平。Introduced hereby is the construction proposal for recovery of Shanghai Rail Transit Line 4, including measures for execution. The recovery work is executed in several sections, i.e. the east and west sides, the open cut middle section, the butt joining section and the two broken sections to be cleaned up. A description is given of the construction of the ultradeep diaphragm wall, cleaning up of ultradeep obstacles, ultradeep strengthening by double high pressure churning and grouting, ultradeep dewatering of confined water, construction of frozen subsurface excavation, etc. The successful completion of the recovery works has raised the technical level of domestic underground construction in soft ground.
