400km/h高速铁路实现3min追踪间隔时间技术条件分析
Technical Analysis for Achieving 3-Minute Train Tracking Interval on 400 km/h High Speed Railways
摘要
Abstract
The development of 400 km/h high speed railways is a crucial direction for China's future high speed rail network.Achieving a 3-minute train tracking interval is a key challenge in the construction of 400 km/h high speed railways.To address this problem,this paper employed theoretical analysis and simulation experiments to analyze the technical conditions required for achieving a 3-minute train tracking interval on 400 km/h high speed railways.In the theoretical analysis phase,based on the block protection technology currently used in China's high speed railway,methods for calculating tracking intervals in three categories:train departure,line section,and arrival,were analyzed,along with the factors influencing them.Key factors with optimization value were selected through considerations of actual route design,operational circumstances,and sensitivity analysis.In the simulation experiment phase,a multi-factor train tracking operation simulation model was established using computer simulation.The goal was to achieve a 3-minute train tracking interval,and a set of technical conditions was determined through the use of the control variable method.The research findings provide valuable reference for studying the achievement of a 3-minute train tracking interval on 400 km/h high speed railways.关键词
