ABSTRACT: The phenomenon of rib spalling in railway tunnel construction referred to the occurrence of spalling in the surrounding rock during tunnel excavation. This was caused by complex geological conditions and engineering technical factors. Rib spalling not only led to the destruction and collapse of the surrounding rock in railway tunnels but also severely affected the stability and bearing capacity of the tunnel structure, which impacted the construction safety and operation of the railway tunnel. In this paper, through the study of the problem of rib spalling, the cause and harm of its occurrence were discussed, and the corresponding prevention measures were put forward. According to different geological conditions and engineering requirements, measures such as strengthening support, pre-treating surrounding rock and optimizing construction method could be taken to reduce the occurrence of rib spalling. In the end, the prospect of the prevention and control of the rib spalling in tunnel construction was put forward. Therefore, through an in-depth study of the causes and hazards of the rib spalling and taking reasonable preventive measures, the occurrence of rib spalling can be effectively reduced, and the safety and reliability of railway tunnel construction can be improved.
