【Abstract】 Based on the background of the starting of a shield on Nanning Metro Line 4, this paper introduces the design and structure of shield starting counterforce frame system, and calculates and analyzes the force mechanism of each component, and uses Midas civil finite element software to carry out numerical simulation analysis, the calculation and simulation are compared with the implementation. The numerical simulation results are closer to reality, and the research results are designed to provide reference for similar construction.更多还原
