摘　　要：某古城区处于市中心,周围交通环绕,地下管线密集,对该一级大型超深基坑支护所采用"整体顺作法"的总体设计、施工及监测进行了理论与实践研究,使实例基坑支护工程能够保证基坑周边建(构)筑物、地下管线、道路的安全和正常使用的功能要求,满足主体地下结构施工空间施工期间的安全功能要求。经主体地下结构施工空间的施工期间观察及基坑监测表明,基坑支护工况良好,可供类似工程参考。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.
