Abstract
Developing countries are still in the stage of infrastructure construction. For the reasons of design and economy, it is inevitable to encounter large section tunnel when building subway and expressway in urban construction. Taking the tunnel project of Central Park East Station of Chongqing Metro Line 10 as the case background, the cross-section optimization and process optimization of each section in the construction of extra-large cross-section tunnel are studied. Based on the principle of analogy analysis, the optimization model of the super-large section tunnel is constructed from five aspects: horizontal stratification optimization, horizontal block optimization, plane partition optimization, longitudinal section optimization and three-dimensional block optimization. Finally, a better excavation scheme than the original design is obtained by using the plane optimization model. Therefore, it can be used as a reference for similar projects to optimize tunnel construction methods.
