摘要:
为提高山区铁路选线的合理性，以沈白高速铁路某区段为研究背景，构建以修正TOPSIS理论为基础的山区高速铁路选线评价模型，选取线路长度、桥隧长度、周边环境影响、工程投资等评价指标，采用修正TOPSIS理论和熵权法对拟采用的3种方案进行优选，结果表明：（1）基于熵权法和修正TOPSIS选线模型中3种方案的推荐度：方案Ⅰ>方案Ⅲ>方案Ⅱ；（2）3种方案的线路长度基本相当，方案Ⅰ线路平面线型略差，但工程投资节省明显，且对村庄拆迁影响更小，线路初选结果为方案Ⅰ（并行抚通高速公路短隧道方案）；（3）基于修正TOPSIS选线模型优选出的方案与实际论证结果一致，本文提出的修正TOPSIS选线模型有一定的合理性和可行性。研究成果可为山区铁路选线设计提供参考。
Abstract:
This study aims to improve the rationality of route selection for railways in mountainous areas. By taking a section of Shenyang-Baihe High-speed Railway as a case for study，an evaluation model of route selection for mountainous high-speed railways based on modified TOPSIS theory was established in the paper. Evaluation indicators such as route length，bridge and tunnel length，surrounding environmental impact，and project investment were selected. The modified TOPSIS theory and entropy weight method were employed to optimize three proposed schemes. The results show that：（1）The recommendation degree of the three optional schemes based on the entropy weight method and modified TOPSIS route selection model is as follows：Option Ⅰ > Option Ⅲ > Option Ⅱ.（2）The route lengths of the three options are comparable，and Option I has a slightly worse planar alignment but significant cost savings in project cost. It also has a relatively smaller impact on village relocation. The preliminary selection result of the route is Option Ⅰ（Running parallel to Futong Expressway with short tunnels）.（3）The scheme selected by the modified TOPSIS route selection model is consistent with the actual demonstration results，indicating that the proposed model has certain rationality and feasibility. The findings can provide a reference for the route selection of railways in mountainous areas.
