Outdoor Wind Environment Evaluation and Optimization Design Strategy of the Proposed Three-Star Green High-Speed Railway Station
This paper took the proposed Hefei West Station as an example,used CFD software Fluent to simulate the outdoor wind environment of the proposed building under typical working conditions,and made a judgement on meeting the standard by combining with the Assessment Standard for Green Building.The results show that:under summer conditions,there is a large area with wind speed less than 0.2 m/s in the north of the high-speed railway station outdoor,and there are a small range of wind speed overrun areas in the northwest and south,with some vortex areas;under winter conditions,areas with wind speeds greater than 5 m/s occur in the pedestrian area,while the wind speed in the outdoor rest area and children's entertainment area is no greater than 2 m/s,areas with a wind speed amplification factor greater than or equal to 2 also appear in the pedestrian area.Based on the current problems of outdoor wind environment,different simulation conditions were established,wind environment optimization design strategies were proposed from aspects of site layout,architectural form,and landscape design.The research can enrich the theoretical framework of green technology in China's transportation buildings,and provide a reference for the green design and transformation of railway passenger stations.
