Abstract:

Deep foundation pit engineering is the core component of the development of underground space in modern buildings.The safety control of its supporting structure involves many aspects，such as engineering stability，personnel safety and environmental maintenance.In this paper，the safety control terminology of deep foundation pit supporting structure is systematically analyzed，and the basic terminology definitions such as foundation pit，supporting structure and design service life are clarified.The structural type terms such as row pile support and underground continuous wall are analyzed，and the groundwater control terms such as water interception curtain and precipitation are interpreted.The key terms are explored，which can provide practical reference for the safety control of deep foundation pit supporting structure.

Key words: deep foundation pit, supporting structure, safety control, key points of terminology, engineering applications
