摘　　要：港深西部铁路是引领港深西部走廊建设的重要基础设施,围绕服务两地旅客快速出行、适应两地技术标准、具备工程经济合理性等目标开展速度目标值研究,对提升该线路服务质量和项目收益具有重要意义。采用调查法、实验法、定量和定性分析法对港深西部铁路速度目标值进行综合比选。首先,对港铁运营线路及大湾区城际铁路的技术标准进行分析梳理,结合本线功能定位,确定速度目标值初选范围。在此基础上,模拟计算各速度目标值区间运行时分,分析其时间目标适应性和站间距适应性,从列车运行角度对比各速度目标值。然后,分析和计算不同供电制式的设施数量、系统匹配性、工程可实施性及建设投资,得出供电制式推荐意见;结合速度目标值比选范围及供电制式推荐方案,计算对应车型平台的车辆购置费和车辆基地规模、建设费用及物业开发收益,从供电和车型角度比较各速度目标值。基于上述比选,全面总结梳理各速度目标值优缺点,最终推荐本项目采用160 km/h的速度目标值方案。研究结论综合考虑了港深两地技术标准、时空距离、项目功能定位、供电制式、车型平台以及工程经济等影响因素,为合理确定本项目速度目标值方案提供了有力支撑,也对港深都市圈城际铁路的速度目标值选择提供参考。The Hong Kong-Shenzhen Western Railway is important infrastructure supporting the construction of the Hong Kong-Shenzhen Western Corridor.This study aims to determine the optimal target speed value,focusing on facilitating fast travel for passengers between the two regions,adapting to the technical standards of both regions,and ensuring economic feasibility.The research is significant for improving service quality and maximizing projects economic returns.Comprehensive comparisons of target speeds was conducted using survey methods,experimental methods,and both quantitative and qualitative analysis.First,the technical standards of the Hong Kong rail network and the Greater Bay Area intercity railways were reviewed.An initial range of target speeds was determined based on the functional positioning of the railway.Simulations were then performed to calculate the interval running time for different target speed ranges,analyzing their adaptability to time and station spacing.Comparisons were made from the perspective of train operations.Additionally,the number of facilities,system compatibility,engineering feasibility,and construction investment for different power supply systems were analyzed,leading to recommendations on the optimal power supply system.Further analysis involved calculating the vehicle procurement costs,depot size,construction expenses,and property development revenue associated with different train model platforms,allowing for comparisons of target speeds based on power supply and vehicle model considerations.Based on comprehensive comparisons,the advantages and disadvantages of each target speed were summarized,and a value of 160 km/h was recommended for this project.The research conclusions comprehensively consider the technical standards,time-space distance,project functionality,power supply systems,vehicle platform,engineering economics and other influencing factors from both Hong Kong and China's Mainland.This provides strong support for the reasonable determination of the projects target speed
