ajst-21814	Guo, Shihao; Mu, Bangbang; Zhao, Mingyang; Wang, Huiyan	Tunnel excavation based on FLAC3d numerical simulation	2024	9	.pdf	application/pdf	2177	176	57	Conclusion After in-depth study of FLAC3D numerical simulation of tunnel excavation process, we draw the following conclusions: (1) During tunnel excavation, the stress distribution of surrounding rock changes significantly. Assuming that the surrounding rock is an ideal elastoplastic material, the following problems are analyzed by using finite element or finite difference method: the arch roof subsidence and the horizontal convergence of the side wall after tunnel excavation under the action of gravity stress field and the size of the plastic zone in the surrounding rock.	cache/ajst-21814.pdf	txt/ajst-21814.txt
