A typical foundation excavation project in Shenzhen is faced with multiple challenges such asultra-deep foundation excavation, adjacent subway planning line and limited site. Based on this project,the key technology of rapid construction of ultra-deep and ultra-large foundation excavation in zeroconstruction site of subway planning control area is studied, and a complete set of key technologies isformed, including support design optimization, rapid construction of retaining piles, rapid construction ofrecyclable anchor cables, rapid construction of earthwork, monitoring and control, precipitation andgroundwater control, quality control and safety management and so on.
