Application of Fabricated Steel Support System Consisting of Prestressed Fish-bellied Beams in the Deep Foudation Pits Near Wuxi Metro
With the development of urban rail transit and its surrounding engineering construction,the safety of foundation pit support around the subway has been given more attention.This paper mainly analyzes the foundation pit support scheme of Sam's Club Project near Wuxi Metro Line 1.The fabricated steel support system consisting of prestressed fish-bellied beams is determined to replace the traditional concrete supporting system,the construction period and cost are greatly saved.At the same time,the finite element analysis and real-time monitoring data of foundation pit verify the safety and reliability of the support system.The large-span steel support system of this project is a new attempt in the deep foundation pit engineering around Wuxi Metro,and also conforms to the concept of green geotechnical engineering.
