- Taking Chongqing Metro Line 5 tunnel project as an engineering example, which is a shallow buried large section tunnel. Study on the length of core soil in the tunnel excavation. The numerical simulation software MIDAS-GTS was used to establish the three dimensional solid model which under different length of core soil. The results were compared with the measured data, and the correctness and effectiveness of the proposed method were verified. The mechanical properties and deformation index of surrounding rock under three different length of core soil were integrated analysis. Finally, the reasonable length of middle wall core soil was determined to be 25 m. The methods and conclusions of this paper can be used as reference for the study of the reasonable length of the middle wall core soil in the flat super large section tunnel. It provided a theoretical support for the construction.
