Structure design draft tube of Xiaoshankou hydropower station

摘要

This The draft tube is one of the main load-bearing structure of the hydropower plant, The hydropower draft tube of Xiaoshankou is an underground space structure, mainly composed by the taper pipe segment, elbows segment and diffusion segment. This paper describe the structure design and calculation process of Xiaoshankou hydropower draft tube, including the draft tube load calculation, structural mechanics just Rigid panels calculate internal force calculation and reinforcement calculation.
