The Xi'an-Shiyan high-speed railway, a major new transport corridor linking central and western China, has incorporated an "ecology first" development model, implementing environmental protection measures throughout its construction.
As an important part of the railway, the 8.39-kilometer Chanhe Grand Bridge in Xi'an spans the Chanhe River and surrounding ecologically sensitive areas. To help minimize the impact on the local environment, the construction team adopted and integrated innovative digital technologies.
"Through 3D modeling of bridge structures and their surrounding environment, we developed an intelligent construction management platform. This system provides holistic and multi-dimensional monitoring and data analysis, significantly mitigating the impact of construction disturbances," said Chen Hongbo, deputy director of China Railway Xi'an Group's construction department.
As the starting station of the high-speed railway, Xi'an East Station also embodies the spirit of green and low-carbon development. The station building adopts a daylighting design that combines glass curtain walls with roof skylights, making full use of natural light to reduce energy consumption.
In addition, vast arrays of solar panels have been installed on the roof to provide clean electricity for station operations.
"We've installed about 30,000 square meters of photovoltaic panels on Xi'an East Railway Station's metal roof. These panels can generate an average of 7.59 million kilowatt hours annually, meaning that around 6,325 tons of carbon emissions can be reduced. The power generated by the panels can meet most of the station's operational power needs," said Wang Lixing, project manager of China Railway Construction Group's Xi'an East Railway Station.
The railway has a designed speed of up to 350 km per hour and a total length of 257 km. It connects Xi'an, capital of northwest China's Shaanxi Province, with Shiyan in neighboring Hubei Province in the country's central region.
The line connects to the existing Wuhan-Shiyan high-speed railway, cutting the travel time between Xi'an and Wuhan, capital of Hubei, to 2 hours 41 minutes, down from the previous 4.5-hour detour route. The trip between Xi'an and Shiyan has been slashed from over 6 hours on conventional trains to barely an hour.
