Abstract：
An ancient urban area is located in the urban center with busy traffic and there are dense underground pipelines. Theoretical and practical studies were carried out for general design, construction and supervision of large super-deep foundation pit supporting by using "overall bottom-up method", to guarantee the safety and normal functional requirements of surrounding structures, buildings, underground pipelines and roads. Safety and functional requirements were satisfied during construction of main underground structure. After construction observation and foundation pit supervision, it was shown that the foundation pit supporting were favorable. References were provided for similar projects.
