    Research on Shield Tunnelling Parameters Correlation in Composite Strata by Ziqi Guo, Huipeng Zhang, Xiaoyang Shi, Zhi Huang, Yiyong Xu, Zhiqiang Zhang

    Published 2022-01-01
    “…Based on the tunnel project between the Dinggong Road North Station and the People’s Park Station online 4 of Nanchang Metro during shield tunnelling construction, this paper collects thrust, torque, and revolution speed of the cutterhead during shield tunnelling in the complex strata with differentiated argillaceous siltstone and gravel and analyzes these parameters by means of mathematical statistics analysis, in order to explore the interrelationship between shield tunnelling parameters under different stratigraphic conditions and put forward optimization suggestions for tunnelling parameters, which can provide a reference for control of tunnelling parameters of earth pressure shield in composite strata.…”
