Abstract：
Due to the high structural strength and rapid assembly construction advantages, corrugated steel plates have been increasingly applied in tunnel shaft support structures. As shafts serve as ventilation channels during the operational period of tunnels, the wall surface resistance directly affects operational energy consumption. To investigate the ventilation resistance characteristics when corrugated steel plates are used as shaft linings, numerical simu?
lations were employed to analyze the influence patterns of key design parameters (such as corrugation depth and
pitch) on ventilation resistance. An optimal parameter combination and a calculation formula for the frictional resis?
tance of steel corrugated plates along the shaft length were proposed. Regarding the influence of the initial installation position of the inlet corrugated steel plate on local ventilation resistance, comparative analyses of the pressure loss patterns for three starting positions—corrugation trough, crest, and mid-wave—were conducted. Furthermore,by establishing local resistance analysis models for different corrugation profiles, the effects of varying corrugation radii on local resistance were revealed. Results indicate that the corrugated plate with a profile of 68×13 exhibits the
lowest frictional resistance along the shaft length. However, considering structural performance, construction convenience, and long-term stability, the 230×64 corrugated plate—having slightly higher resistance—is recommended.For inlet corrugation starting position, the crest is preferred, resulting in only 54% of the ventilation resistance compared to starting at the trough. For the 230×64 corrugated plate, it is recommended to optimize its radius to 52 mm,which can reduce the frictional resistance coefficient to 48% of that obtained using the code-specified radius (57 mm).
