| Abstract: | For shield tunneling in the soft-soil area, in view of the soil mass failure and creepage caused by shield tunneling setting out, during the construction of the tunnel between Pudong Wide Road station and Zhangyang Road station of the Shanghai Rail Transit Pearl Line Stage 2, in order to assure a safety and normal usage of the underground pipelines and ground buildings, artificial soil freezing reinforcement method was applied to the shield tunneling setting out for the first time; and it has achieved good effectiveness. This article describes the project in detail, for instance, the choice of reinforcement scheme, key technologies and the practical effectiveness of this method; and discusses the applied prospect of artificial soil freezing reinforcement method for underground engineering in aqueous soft-soil area. |
