英文摘要	To address the problems of easy collapse and excessive displacement of the support structures of shallow-buried bias tunnels during construction of an existing tunnel section, a new protective structure for the shallow-buried bias tunnel at the portal section was proposed. The advantages of anti-slide piles, anchor cables, and pipe sheds were considered and utilized for the cross-construction. The simplified analysis model of the protective structure under terrain bias was established, and the internal force and displacement of the protective structure under terrain bias were solved using the M method. Then, the internal force and displacement of the structure under the combined action of terrain and construction bias were corrected and obtained by the deformation coordination condition. Combined with the example model, the internal force and displacement distributions of the new protective structure were analyzed. The reliability of the simplified calculation method was thus verified by comparing the calculation results and the ADINA simulation results, which provides a theoretical basis for the analysis and design of similar new structures. © 2018, Editorial Department of China Journal of Highway and Transport.
