On October 21, the official website of Xi'an Rail Group released a second announcement of the environmental impact assessment information of Metro Line 8 project, and solicited opinions from the public. The "Draft for Soliciting Opinions for Project Environmental Impact Report" released this time released more details of Line 8.
The only ring line in the network is 49.896km in June 2019, the National Development and Reform Commission issued the "Approval on Xi'an Urban Rail Transit Construction Plan (2018-2024)", agreeing to the planning and construction of Line 1 Phase 3 and No. 2 There are seven projects including Phase II, Line 8, Phase I of Line 10, Line 14, Line 15, and Phase I of Line 16, with a total length of about 150km.
Among the third phase planned network, the most popular among citizens is Metro Line 8. As the main skeleton line of Xi'an urban rail transit network, Metro Line 8 is the only ring line in the network. The line runs through five administrative districts including Yanta District, , Xincheng District, Baqiao District, , Weiyang District, and Lianhu District, as well as four development new districts including Hi-tech Zone, Qujiang New District, , Xi'anba Ecological Park, and Economic Development Zone.
According to the latest environmental impact assessment report, Metro Line 8 is 49.896km long, all of which are underground lines, along Zhangba East Road, Yanzhan Road, Yannan Fourth Road, Hanyao Road, South Third Ring Road, Changming Road, Xingfu Forest belt, Guangyuntan Avenue, Xiangba 1st Road, Fengcheng 2nd Road, Zhuhong Road, Daxing Road, West Second Ring Road, Fenghui Road and Tangyan Road were arranged.
has a total of 37 stations. 18 transfer stations.
Metro Line 8 has a total of 37 stations, including 18 transfer stations. The maximum station spacing between is 2529m, located in Mingguang Road-a total of 37 stations and 18 transfer stations-Fanjiacun section, with the minimum station spacing of 790m, located in the electronic street-Dongyi Road section, with an average station spacing of 1.349km. Line 8 forms multiple transfers with the lines in the network, which is an important transfer route in the network, and has outstanding transfer function.
reporter sorted out the transfer stations of Line 8 and found that the transfer stations of Electronic City Station, Wangjiafen Station and Line 7 transfer, Dongyi Road Station and Line 11 transfer, Exhibition Center Station and , Municipal Library Station and Line 2 transfer, Qujiangchi West Station, Yujiazhai Station and Line 4 transfer, Changming Road Station, Xintaoyuan Station and Line 5 transfer, Wanshou South Road Station, Zhijiazhai Station and Line 6 transfer Take the transfer, Guangtaimen Station, Yanpingmen Station, and Line 3, Baozicun Station and Line 19, Yangjiazhuang Station and Line 10, Kaiyuanmen Station and Line 1, and Zhiliu Road The station transfers to Line 6 and Line 11.
Metro Line 8 sets the Changming Road depot on the east side of Changming Road and the south side of Dongyue Road, and sets the Huanyuan Middle Road parking lot on the north side of Fengcheng 5th Road and the west side of Beichen Avenue. A new main substation was built across the line, sharing Line 1 Huancheng Xiyuan, Line 2 Convention and Exhibition Center, and Line 5 Rongjiazhai Main Substation. The control center is located in the Changming Road Vehicle Depot plot on Line 8 Changming Road.
uses A-type vehicles. The entire line runs on the main transportation roads. According to the environmental impact assessment report, Line 8 will use domestic A-type vehicles, all of which adopt 6 marshalling schemes, 4 dynamics and 2 tows, and the maximum operating speed of trains is 80km/h.
According to the passenger flow forecast of Line 8 and the analysis of the network service level matching, Line 8 adopts the operation mode of one large road in the entire line. The operating time of is planned to be from 5:30 to 23:30 am, and operates for a total of 18 hours throughout the day. . According to the schematic diagram of the environmental impact assessment report, the inner ring of Line 8 runs clockwise and the outer ring runs counterclockwise.
Additional Dabaiyang Station
Adjustment of the direction of the section from Qujiangchi West to Yanxiang
Relevant departments further investigated and analyzed factors such as environmental sensitive points, geological conditions, engineering construction conditions, and local relevant departments along the route, and conducted local routes and station settings. Further research and optimization and adjustment were carried out.
is designed to drive the development of surrounding plots, facilitate surrounding passenger flow, and support surrounding commercial development. In combination with the needs of Lianhu District Government, this design adds one station - Dabaipo Station - in the largest station spacing section of the entire line (Hongmiaopo - Xiaobaipo Zone). The northeast quadrant of Dabaiyang Station is the office building and parking lot of Shaanxi Communications Service Co., Ltd. (Zhongjie Science and Technology Branch); the southeast quadrant is the Blue Flower City Community; the southwest quadrant is the private house along the railway and the railway work team room; the northwest quadrant is the park mansion community.
is a reasonable layout of line stations, effectively connecting many passenger flow distribution points, ensuring the safety and feasibility of the project, and at the same time, starting from factors such as small interference with surrounding buildings, in this design, the route of the Qujiang Chixi to Yanxiang section is from the planning environmental impact assessment stage Yannan Fifth Road was changed to Hanyao Road. After adjustment, the line was straight and did not penetrate the existing vibrating buildings. The project was highly implemented and the operating conditions were better. The rest of the road sections have not changed.
involves 3 cultural relics protection units
uses shield structure method to reduce the impact
According to the draft for environmental impact assessment, Metro Line 8 involves Han Chang'an City ruins (the ground ruins of Han Chang'an City and the Tangbiyong site), and the Chang'an City ruins of Sui and Tangtang ( Yanpingmen ruins and Temple of Heaven ruins), Duling 3 cultural relics protection units.
8 will pass through the Han Chang'an City Ruins in the form of a tunnel and the construction control zone of and the landscape coordination zone, the Sui and Tang Dynasties Chang'an City Ruins in the form of a tunnel, the Duling general protection scope, construction control zone and environmental coordination zone. Before the construction of these areas, detailed archaeological exploration and investigation will be carried out, and the subway will be carried out through the Han Chang'an City ruins in the form of a sectional tunnel. The construction of sectional tunnels adopts the shield method with the least environmental impact and the most effective settlement control, so as to minimize the The impact on the site, and at the same time, try to increase the burial depth to reduce the impact of vibration on cultural relics.
