崩塌滑坡灾害对川藏铁路康定—昌都段选线的影响

线路选线是铁路工程设计与建设中一项关系到全局的总体性工作,线路走向是否合理,直接关系到铁路本身的工程投资和运营效果。地质灾害是影响铁路选线最重要的因素。通过滑坡崩塌灾害对线路的影响分析,可最大限度避免线路经过严重地质灾害地段,规避重大工程风险。通过对川藏铁路康定—昌都段沿线崩塌滑坡灾害调查和量测,结合遥感解译成果,主要考虑沿线崩塌、滑坡灾害的影响,给出关键区段、节点的铁路地质选线策略,对比规划线路,提出基于崩塌滑坡灾害影响的建议线路。

The Influence of Landslide and Collapse Hazards on Railway Alignment in Kangding-Changdu Section of Sichuan-Tibet Railway

Railway route selection is an integral work in railway engineering design and construction and is very important to the whole system. The alignment is directly related to the project investment and operation and geological hazards are the most important factors affecting the railway route selection. First of all,through the analysis of the impact of landslide and collapse disaster on the railway alignment,serious geological disasters and major engineering risks can be avoided to the maximum. Furthermore,geological alignment tactics are concluded based on the investigation and measurement of the landslide and collapse hazards along Kangding-Changdu section with reference to the results of remote sensing interpretation. Finally,compared with the planned route,the route based on the impact of collapse and landslide disaster is recommended.
