Abstract: The ring beam supporting structure is a special form of internal supporting system. Based on a case history, characteristics of the ring beam supporting structure are analyzed, and the structure design and construction aspects of the system are also introduced in the paper. The critical issues that might affect the design and construction and their solutions are pointed out.

Key words: deep excavations, ring beam supporting system, deep excavation design
