taihang mount tunnel

Taihang Mountain Tunnel is the longest mountain tunnel in China at present. It is a double-hole single-track tunnel, passing through Shaoshan, the main peak of Taihang Mountain, with an altitude of 13 1 1 m. The maximum buried depth is 445 meters, and the distance between the two lines is 35 meters. The total length of the left line is 27839 meters, and the total length of the right line is 27848 meters. At the end of 2007, the whole line was connected.

The geological structure of Taihang Mountain Tunnel is complex and prone to collapse and large deformation. During the construction process, the Taihang Mountain Tunnel optimized the construction organization after docking with the construction, design, supervision and construction units, and adopted the drilling and blasting method for construction. The whole tunnel has 1 entrance, 9 inclined shafts, 1 exit * * *1construction passage, and 24 working faces are constructed at the same time. At the same time, we strengthened scientific and technological research, set up a scientific and technological research team, and organized a number of national tunnel experts to carry out on-site listing research around eight key topics, which accumulated valuable experience for the construction of extra-long and large tunnels in China.

Shijiazhuang-Taiyuan Railway Passenger Dedicated Line is the first passenger dedicated line in China, with a total length of 189.93 km. Construction started on June 65,438+065,438+0, 2005, and it is planned to be completed by the end of 2008. After the completion of Shijiazhuang-Taiyuan Passenger Dedicated Line, it is expected to send passengers150,000 passengers and 40 million tons of goods in one direction every year at the initial stage of operation, which has played a very important role in promoting the coordinated development of regional economy in Shanxi and Hebei provinces and ensuring the transportation of national key materials.
