(2) From the perspective of career prospects, there are more bridge employees and fewer tunnel employees, and the demand for these two industries is still great. In short, with the peak of high-speed rail construction, employment is not a problem.
(3) Supplement: Bridges and tunnels are in high demand in the south and Yunnan-Guizhou-Sichuan area, especially for the construction of high-speed rail, more than 90% of tunnels or bridges are needed. Nowadays, the subway construction in China is getting worse and worse. Several cities started construction at the same time. 10 September, Changsha 1 Line started. 10 In September, Chengdu Metro 1 Line was completed and opened to traffic, Line 2 started construction, and Line 4 began planning and design. Before the opening of the 20 10 Asian Games, Guangzhou Metro will reach 222KM (including Guangzhou section of Guangfo Line), and the long-term planning length is 600 km, which shows that there is still a big gap in the technical personnel in the domestic subway field. Most subways in China are built by shield method, and Southwest Jiaotong University is in a leading position in China. The tunnel under construction by the Ministry of Education has developed two shield machines with diameters of 80CM and 2 m respectively as experimental tools, which is the only full-real shield machine owned by universities in China. Southwest Jiaotong University is definitely in an advantageous position in this field. Compared with the construction of mountain tunnels, bridges and railways, subway construction sites are all in cities, with relatively good living conditions and long construction period, and construction technicians have greater advantages in life and family.
