Abstract:The construction method, bracing and retaining structure and main structure for Shenzhen Futian subway station of Guangzhou，Shenzhen，Hong Kong high，speed rail were briefly introduced. Taking the impact of the soil around the construction on stress and deformation of the structure into account, the spring element was used to simulate the action between the soil and structure, and topdown construction and operation stage of the structure were analyzed by finite element program, which can get more accurate results and provide a reference for similar projects.
Keywords:underground structure；topdown construction method；bracing and retaining structure
