          The extremely complex geological conditions and climatic environments bring great challenges for HSR construction in China. Devoid of proven experiences from other countries, China has formed unique engineering and construction technology advantages through its independent innovation. China has thereafter built a great number of world-class mega projects of HSRs, resistant to special climates such as alpine cold, high temperature, drought and sandstorm, and also under complex geological conditions including mollisol, loess, seasonally frozen ground and karst.

     China has erected numerous world-class long-span HSR bridges over rivers and straits, including the Nanjing Dashengguan Yangtze River Bridge, the world’s first six-track railway bridge; the Shanghai-Suzhou-Nantong Yangtze River Rail-cum-Road Bridge, the worlds first cable-stayed bridge with a main span of more than 1,000 meters; the Wufengshan Yangtze River Bridge, the first HSR suspension bridge also with the largest design load and the highest design speed in the world; the Pingtan Strait Rail-cum-Road Bridge, the worlds longest strait-crossing highway-railway bridge traversing one of the three well-known stormiest sea areas on earth; the Danyang-Kunshan Super Major Bridge on Beijing-Shanghai HSR, spanning 165 km totally as the longest in the world.

     China has bored through more than 100 long and large HSR tunnels for a length of more than 10 kilometers each, including the Shiziyang Tunnel on Guangzhou-Shenzhen-Hong Kong Express Rail Link, the Qinling Tunnel Group on Xian-Chengdu HSR, and the New Badaling Tunnel on Beijing-Zhangjiakou HSR, among which Qinling Tunnel Group along Xian-Chengdu HSR is highlighted with its total length of 134 kilometers.

     China has also built a large array of modern integrated passenger transport hubs, such as Beijingnan Railway Station, Beijing Fengtai Railway Station, Shanghai Hongqiao Railway Station, Wuhan Railway Station, Guangzhounan Railway Station, Xiongan Railway Station, Chongqingxi Railway Station and Hangzhouxi Railway Station, serving as new representations for railway services and new portals for boosting city development. Opened to public in June 2022, Beijing Fengtai Railway Station accommodates a station building up to a floor area of 400,000 square meters, equivalent to 56 standard football fields, and presents a comprehensive three-dimensional traffic mode, namely, “high speed railway on top, conventional railway on the ground level and subway under the ground”, becoming the largest railway hub passenger station in Asia.
