Abstract:

At present, 1D models are usually used in the structural design of Metro stations. Due to the limits of the 1D models, however, the stress on the structures can sometimes not be really understood. The calculation results of 3D models and 1D models under different conditions are compared and analyzed in this paper, so as to find out the limits of 1D models, understand the stress on the Metro station structures as exactly as possible and make 1D models to serve for the technicians more efficiently. The analysis results can provide references for the engineers.

Key words: Metro station constructed by cut and cover method, 1D model, 3D model
