Taking Xi.＇ an-Chengdu Passenger Dedicated Line （PDL） as the background, the paper summarizes several familiar types of tunnel portal and tunnel hood for PDL, and presents a new design concept with a parallel gallery as the compression air wave buffer which is applicable for a tunnel portal with extremely high-steep slope. Based on numerical simula- tion analysis and comparison, the detailed parameters for the buffer structure are illustrated, which are expected to be further discussed and studied and to be offered as a reference for similar project.
