Abstract: With the rapid development of mountainous highways and high-speed railways in China, geological disasters caused by new tunnel excavation, such as landslides, are widespread. Meanwhile, the diseases caused by landslides in existing tunnels are also increasing, resulting in significant harm to the tunnel construction and operation. In this paper, the academic research status, existing problems, and the development prospects associated with the tunnel-landslide system were summarily all over the world. First, the relative spatial location relationship and deformation characteristics of the tunnel-landslide system were systematically investigated. Second, the detailed analyses of the current status and prospects of research on tunnel-landslide interaction from five aspects geological survey, theory, model test, numerical simulation and field monitoring. Then, the control and protection techniques of the tunnel-landslide interaction were expounded from landslide reinforcement, tunnel reinforcement, and monitoring and prediction technology, and the corresponding shortcomings in the existing research and the aspects that still need to be discussed were marked. Finally, it is recommended to carry out further research on the landslide soil plasticity, nonlinear contact, earthquake and rainfall multi-factor coupling effects, the development and utilization of centrifugal model tests, the applicability of constitutive models, and the fine modeling of tunnels. Also, the impact zones of tunnel excavation should be further optimized, and the corresponding novel control and protection technologies should be developed. On this basis, a new type of monitoring technology system linked and shared for tunnel-landslide can be thus established. This paper provides new perspectives and essential data for academic research on tunnel-landslide system engineering.
