Analysis on Tunnel Design Characteristic of Tourism Rail Transit in Scenic Area

Restricted by the connection and the terrain characteristics of scenic area, the tunnel design of tourist rail transit in scenic area presents different characteristics.Based on a tourist rail transit project in a scenic area, the selection of rail transit system for large longitudinal slope tunnel is clarified through the multi-index analysis of rail transit system.The rockfall at the tunnel portal is simulated by finite element software, the rockfall trajectory, distribution range and impact capacity are analyzed, and the tunnel transportation organization scheme, the tunnel portal protection design and the landscape design are discussed.
