摘要
通过计算和实测特大断面隧洞采用短台阶法施工时的受力,得出隧洞断面位移和应力的变化规律及最不利点,可为大断面隧洞的设计与施工提供重要依据,从而进一步提高大断面隧洞的设计和施工质量。
Through calculating and measuring the stress of large section tunnel adopted short bench cut method construction, the tunnel section displacement, stress change law and the worst unfavorable point were obtained, which provided important reference for large section tunnel design and construction, therefore further enhanced large section tunnel design and construction quality.
