Research on the Reconstruction Plan of Pinghu South-Yantian Port Railway
Research purposes:The Pinghu South-Yantian Port Railway,located in Longgang and Yantian districts of Shenzhen,primarily handles the container transportation for Yantian Port's sea-rail intermodal operations.Due to the low technical standards of the existing line,it has become a bottleneck constraining the capacity of the Pingyan transshipment system and it's necessary to enhance the capacity of the Pinghu South-Yantian Port Railway.The urbanization level along the Pinghu South-Yantian Port Railway is high,making the reconstruction of the existing line a complex task with many controlling factors.This paper primarily studies the reconstruction plans for the Pinghu South-Yantian Port Railway,exploring the research approach and principles for reconstructing existing lines in developed areas.Research conclusions:(1)Although the underground double-track scheme along the existing route has increased investment,the new double-track standard raised to 120 km/h can improve the efficiency of goods assembly and distribution.(2)considering the high level of urbanization,dense population,and extremely high urban land development intensity in Shenzhen,along with numerous controlling factors and extremely complex construction environment within the route,New double-track plan for underground construction along existing channels uses a tunnel through the urban area,which can reduce the impact on the city,save land resources,and align with urban planning and detailed project planning.(3)The research recommends adopting the new double-track plan along the existing route.(4)The results of this study are applied to the survey and design of the the Pinghu South-Yantian Port Railway renovation plan,which is consistent with the project feasibility study approval plan.
