摘　　要：大万山隧道设有两道通风斜井,长度共计3155m。原设计斜井中隔墙采用钢筋混凝土结构。鉴于钢筋混凝土中隔墙施工进度较慢,延缓整体工期,故文章提出将中隔墙优化为波纹钢板中隔墙的设计方案。该优化方案契合国家推广使用钢结构的理念,可降低施工难度,加快施工进度。经过结构受力验算,采用波纹钢板中隔墙满足受力要求,该方案具有可行性。Dawanshan tunnel is equipped with two ventilation inclined shafts,with a total length of 3155m.The reinforced concrete structure is adopted in the original design of the middle partition wall of the inclined shaft.Considering the slow construction progress of the middle partition wall ofreinforced concreteand the delay in the overall construction period,the design scheme to optimize the middle partition wall into the middle partition wall of corrugated steel plate is put forward.This optimization scheme is in line with the national concept of promoting the use of steel structure,which can reduce the construction difficulty and accelerate the construction progress.After the checking calculation of structure stress,the middle partition wall of corrugated steel plate meets the stress requirements.This scheme is feasible.
