摘要
国内齿轨铁路的研究尚处起步阶段,由于其采用齿轮传动力克服了轮轨黏着极限,在地形起伏较大的山地型城镇(社区)、山区旅游交通线路中具有较强的适用性。以湖南省某工程为实例,创新性地利用低空机载LiDAR技术,提出一种复杂地形下现代齿轨铁路的线路设计方法:(1)齿轨铁路选线应首先根据自然特征和工程技术要求确定合理的技术标准,再结合功能定位及其他因素综合确定线路走向方案;(2)对于旅游交通,线路方案综合比选中要充分考虑旅游观光属性,满足旅游客流特点;(3)机载LiDAR技术通过区域点云采集、数据处理、点云融合及对植被、建筑物等非地表点的过滤后形成成果,可较为精准、直观地获取地形、断面数据,辅助局部方案的优化以及重难点方案的决策。
The research on the rack railway in China is still at the early stage.As it overcomes the wheel rail adhesion limit by using gear transmission power,the rack rail is mainly applied to mountainous towns and tourism traffic lines.Taking a project in Hunan Province as an example,this paper proposes a design method for rack railway line in complex terrain by using the low altitude airborne LiDAR technology.(1)The reasonable technical standards shall be defined according to the natural characteristics and engineering technical requirements,and then the route scheme shall be determined based on functional positioning and other factors;(2)For tourism traffic,the route scheme should fully consider the attribute of tourism and the characteristics of tourist flow;(3)With the regional point cloud collection,data processing,point cloud fusion and filtering of non-surface points such as vegetation and buildings,airborne LiDAR technology can assist the optimization of local schemes and the decision-making of difficult schemes.
