Design Study on the Prefabricated Partition Walls for Single-hole Tunnel with Two-tracks of City Line
The middle partition wall is the key component to realize the single-hole and double-line layout of the tunnel,and the current research focuses on the construction technology and mechanical performance of the middle partition wall,and pays little attention to its design scheme.In this paper,based on the prefabricated partition wall structure of Shanghai Municipal Airport Liaison Line,the design scheme is studied,so as to reduce the impact force of impact load on the middle partition wall,and ensure the reliability of the top node in the construction and operation process,so as to avoid the failure of the top node.
