Abstract

Abstract:

Taking the crosssection lining of 200km/h GanzhouShaoguan single track railway tunnel as research objective, the author introduces the influence rules of many factors on the internal force of tunnel lining by means of numerical simulation. These factors include surrounding rock pressure percentage, elastic reaction coefficient, secondary lining thickness, cover depth of shallow buried tunnel and surface gradient of asymmetricallyloaded tunnel. This paper can provide references for the design and optimization of 200km/h railway tunnel lining in the future.
