Xinhua, January 21, 2020

Construction of the longest undersea subway tunnel in China was completed Monday in Qingdao, a coastal city in Shandong Province.

The 5.4-km-long tunnel, between the stations of Dayang and Qingdao North, is part of the Subway Line No. 8 project in Qingdao.

The eastern side of the tunnel was dug by the slurry shield method, while the western side by the mining method, said Wang Zili, chief engineer of the project with the China Railway Group, the company responsible for the construction.

Multiple measures, including the utilization of a robotic arm, were adopted to avoid water and mud bursts, Wang said.

The tunnel has surpassed the cross-sea tunnel of the Qingdao's Subway Line No. 1, which has 3.49 km of the line undersea, becoming the longest undersea subway tunnel in China, according to the China Railway Group and the Qingdao Metro Group, operator of the subway lines.

The Subway Line No. 8, which will run 61.4 km with 18 stations designed, will connect the international airport of Jiaodong and railway stations of Jiaozhou North, Hongdao and Qingdao North, linking the city proper of Qingdao, the economic zone of Hongdao and the city of Jiaozhou.

Xuzhou Approves USD7.7 Billion Subway Plan as Regulators Get Back to Work


(Yicai Global) Feb. 11 -- The National Development and Reform Commission, China's top economic planner and price setter, has approved a CNY53.6 billion (USD7.7 billion) urban rail transit plan in Xuzhou as authorities begin to return to work following the Chinese New Year holiday, which was extended due to the outbreak of the novel coronavirus from Wuhan.

The rail program includes the second phase of Line 3 of city's subway and the first phase of Lines 4, 5 and 6, the NDRC said online yesterday. The work is scheduled to be completed in 2024 and will be 40 percent funded by the local finance department, with the remainder coming mostly from bank loans with some other borrowing.

China pushed back the return to work of many companies after the Chinese New Year following an outbreak of a new coronavirus that claimed 100 lives yesterday and now has a death toll of over 1,000, according to official data. A large number of organizations are asking employees to work from home in a bid to prevent further spread of the disease.

There are still a lot of shortcomings in China's infrastructure and public service sectors, especially as the economy is undergoing a new phase of transformation, Ding Changfa, an associate professor at Xiamen University's economics department, told Yicai Global. The population is flowing rapidly into central cities and transit development can ease traffic and accelerate the flow of people and goods, he added.

Xuzhou opened its metro system in September and has two lines under construction. Ultimately, it will have 11 lines spanning 323.1 kilometers, with seven lines in the central urban area and four express routes in the outskirts.

There were 40 Chinese mainland cities with subway systems as of the end of 2019, with a total length of 6.7 million kilometers. The NDRC approved three new metro construction plans last year, in Zhengzhou, Xi'an and Chengdu, covering 486.3 kilometers with investment of CNY342.6 billion.
