Abstract

Abstract: The design parameters of composite lining with its primary support as the loadbearing structure are studied, with Xiangshan tunnel and Qingtiansi tunnel on BaotouLanzhou railway as examples. The study methods and study results are presented. The optimized parameters of the tunnel structure with its primary support as the loadbearing structure are presented. The paper can provide reference for similar projects in the future.

Key words: tunnel, primary support, loadbearing structure, composite lining, design parameter
