简介：摘 要：地方铁路连乐铁路在燕岗车站接入成昆铁路，从而实现与国铁路网的互联互通。燕岗地区同时开工建设的项目有燕岗车站的扩能改造及成昆增建双线工程，在这样一种特殊的历史背景下，更增添了该处接轨方案的不平凡和特殊色彩。接轨方案从2013年开始报批至2021年铁路总公司才最终予以审定，期间各种审查，修改，完善，蜿蜒曲折、辗转反侧，也充分反映了该方案的复杂性。本文从方案的研究思路出发，综合考虑既有铁路、在建铁路、本线特点，以行车组织为导向的前提下，寻求最终经济合理的工程方案。

简介：在这篇论文，我们为在铁路网络上模仿火车运动建议一个改进散步模型。在建议方法，行人们代表火车。改进散步模型是一种基于网络的模拟分析模型。用行人运动的一些管理规则，行人能动态地在车站决定它的离开和到达时间。以便测试建议方法，我们在铁路网络的部分上模仿火车运动。数字模拟和分析结果证明改进模型是为在铁路网络上模仿火车运动的一个有效工具。而且，它能很好捕获在铁路交通安排的火车的典型行为。
