Abstract: Tunnel boring machine(TBM)has been widely used in China's coal mines in recent years, and in the process of mining deeper coal seams, the anchor support problem is the main factor causing delays in TBM tunneling.Therefore, an assembled closed roadway support structure(FERSS)suitable for TBM tunneling is proposed, and a full-scale model test under uniform loading conditions is carried out.Conventional monitoring techniques and a new photographic deformation monitoring system were used to investigate the strain and deformation of the model.It can be seen that the deformation of the model is negligible during the test; near the end of the test, the displacement of the model increases sharply, and then the model failures immediately, and the bearing capacity of the model decreases significantly from 6 454.09 kN to 3 481.21 kN when the lateral coefficient is increased from 1 to 2.In addition to verifying the conclusions obtained from the test through numerical simulation, it is concluded that the increase of the lateral coefficient intensifies stress concentration and increase the axial force and bending moment near the weak part.
