景区旅游轨道交通隧道设计特点分析

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

受景点衔接情况、景区地形特点的制约,景区旅游轨道交通隧道工程设计呈现差异化特点。依托某景区旅游轨道交通项目,通过对轨道交通系统制式多指标分析,明确大纵坡隧道轨道制式选型。采用有限元软件对隧道洞口进行落石模拟计算,对落石轨迹、分布范围、冲击能力进行分析,探讨了隧道运输组织方案、洞口防护设计和洞口景观设计的思路。

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.
