Displacement control method for arch ring of hyperbolic large-span cultural relic aqueduct reinforced by pier in reconstruction

The invention relates to the technical field of hydraulic engineering, in particular to a displacement control method for an arch ring of a reconstructed middle pier reinforced hyperbolic large-span cultural relic aqueduct, which comprises a main arch ring: a steel bar is fixed on the side wall of the main arch ring through a bolt, a stainless steel plate is fixed at the bottom of the steel bar, and the stainless steel plate is erected at the top of a fixed elevation position; a stainless steel plate is fixed to the side wall of the main arch ring through steel bars, and the distance between the stainless steel plate and the fixed elevation position is smaller than 10 cm; a thermometer is fixed on the steel bar side wall. In the local reconstruction and reinforcement construction process, the displacement of the arch ring can be detected for many times, real-time displacement monitoring is achieved, accurate control over the displacement distance is facilitated, and the situation that reinforcement fails due
