| Abstract: | In view of the major influential factors in the tunneling process, the paper overcomes the shortcomings of the conventional static plane model, sets up 3-dimensional analytical model with finite element analytical software, and simulate the tunneling process by the single-element life-death technology. It further discusses the shift of the head and bottom plates and that of the two sides in the tunneling process as well as the evolution of the stress field and shift field so as to provide a basis of theoretical analysis for the design of protective support. |
