Abstract:
Aiming at the construction technical requirements of shallow large span subway stations in upper-soft and lower-hard stratum, the fusion of double side wall guide pit method and dome method, a construction method for shallow large span subway stations suitable for upper-soft and lower-hard stratum is proposed. On the basis of extracting some innovative technical content, a set of construction technology for shallow large span subway stations in upper-soft and lower-hard stratum is developed. Through the engineering application case, the specific construction procedures and construction parameters are given.
