[摘 要] 目前高层建筑地下室面积越来越大，深度越来越深，支护结构与高层建筑地下主体结构相结合已成为深基坑主要的发展方向之一。结合具体的工程实例，探讨高层建筑地下主体结构与基坑支护结构相结合的设计与工程应用，并对主要的监测结果进行分析。工程的设计与实践可以为以后类似与支护结构相结合的高层建筑地下结构的设计施工提供参考。

Abstract：The temporary substructure of high-rise building combined with retaining and bracing system has commonly used in many larger and deeper foundation excavations．How to combine temporary retaining and bracing system with substructure of the actual construction project of a high-rise building was discussed．Performance of the wall based on the instrumentation results were also presented and discussed．Design and practices of the engineering provides a new engineering design choice for the similar pits．

Keywords：substructure combined with retaining and bracing system; reverse construction;substituting level bracing system by basement slab
