Abstract: The design of shed-tunnel structure in the confined environment can help to avoid the safety of passing vehicles and pedestrians from being threatened by the impact of upper rockfall in highway, railway, and other rockfall disaster protection engineering. Due to the limitation of the space environment, it is necessary to optimize the shed-tunnel structure to provide enough space for passing vehicles and pedestrians. In this study, a case study was made on the passing shed tunnel of Badong Juebitianhe Revolutionary Education Base. First, the theoretical calculation of rockfall impact force was compared and optimized. Then, the optimization scheme of “column + anchor bolt + buffer layer†was proposed based on the commonly used shed-tunnel form and was verified by ABAQUS numerical simulation. The performance of the optimized shed-tunnel structure is greatly improved in terms of the space utilization rate of shed tunnel and the impact resistance of rockfall.
