Influence of portal excavation of shallow-buried bias tunnel on stability of soil‒rock bedding slope: a case study of Moziping tunnel by Tao Li, Yue Li, Jiajun Shu, Shiming Hu, Bo Liu

“…A research approach that combines theoretical analysis, numerical simulation, and field monitoring is adopted to systematically investigate the impact mechanism of tunnel excavation on the stability of soil‒rock bedding slopes. A mechanical model of a tunnel–soil–rock bedding slope is established on the basis of the transfer coefficient method, and a slope stability evaluation method suitable for composite strata is proposed. …”
