1 INTRODUCTION

The proposed approach aims at simultaneously optimizing 3-D alignments and station locations for a dedicated high-speed railway link between two selected terminal stations. The optimized design of the 3-D alignment for the high-speed link builds on the recent work of the same authors on mountain railway alignment optimization (Pu et al., 2019). The problem of optimizing station locations along a railway route is new and inherently connected with the problem of railway network design and line planning. The latter problem of railway network design and line planning, however, has been neglected in the above approach and generates suboptimal solutions of the alignment design, as well as of the station locations for a (high-speed) railway route.

讨论 Song, T.、Pu, H.、Schonfeld, P.、Zhang, H.、Li, W. 和 Hu, J. (2021)，同时优化 3-D 路线和车站位置，用于专用高高速铁路，计算机辅助土木和基础设施工程，37(4)，2022 年 3 月

1 简介

所提出的方法旨在同时优化两个选定终点站之间的专用高速铁路连接的 3-D 路线和车站位置。高速链路 3-D 线形的优化设计建立在同一作者最近关于山区铁路线形优化的工作（Pu 等人，2019 年）的基础上。沿铁路线优化车站位置的问题是新的，并且与铁路网络设计和线路规划问题有内在联系。然而，铁路网络设计和线路规划的后一个问题在上述方法中被忽略了，并产生了路线设计以及（高速）铁路路线的车站位置的次优解决方案。
