Abstract
A method for determining parameters of cross sections of a single-hole four-lane highway tunnel includes the steps of determining surrounding rock pressure, constructing numerical models under different flatness ratios, calculating interval force of lining structures, calculating safety coefficients of the lining structures, performing contrastive analysis on the cross sections under different flatness ratios, obtaining reasonable cross section forms, and so on. This method provides a basis to formulate the specifications and standards for design of a single-hole four-lane highway tunnel and may provide a reference basis to design a cross section of a single-hole four-lane highway tunnel in new construction or reconstruction and expansion, thereby ensuring safety and economic efficiency of the cross section forms of the single-hole four-lane highway tunnel.
