ajst-17939	Qin, Chengzhi	Study on the Deformation Characteristics of Different Excavation Methods for Class V Perimeter Rock Tunnels	2024	5	.pdf	application/pdf	2532	90	43	Keywords: Numerical simulation; Excavation method; Envelope deformation; CD method; Soft rock tunnels. Among them, Ⅳ, Ⅴ weak surrounding rock due to its poor lithology, easy to occur large deformation, improper treatment will bring great potential danger to the construction safety, so the study of large deformation of soft rock tunnels has been a hot topic.	cache/ajst-17939.pdf	txt/ajst-17939.txt
