Chengdu Guiyang high speed railway runs through the whole line to promote the diversified development of Sichuan Guizhou interaction

On December 16, 2019, the Yibin Guiyang section of Chengdu Guiyang high speed railway was put into operation, marking the completion and opening of the whole Chengdu Guiyang high speed railway. After 11 years, Chengdu Guiyang high-speed railway finally opened to traffic. Chengdu Guiyang high speed railway is 648km long from Chengdu east railway station to Guiyang east railway station. It has 24 stations. It only takes 2 hours and 58 minutes from Chengdu to Guiyang. Chengdu Guiyang high speed railway connects the features and culture of Sichuan and Guizhou. In the morning, I had a hot pot in Chengdu and had a taste of brown sugar ice powder in Guiyang at noon. In the morning, I saw the magnificent scenery of Sichuan, and in the afternoon, I saw the beautiful scenery of Guizhou. Sichuan Province is dominated by basins, while Guizhou Province is dominated by plateaus. The difference between the two landforms should form different beautiful sceneries. Sichuan people have never lived in the plateau area, on the contrary, Guizhou people have never felt the appearance of the basin. So whether it's Leshan Giant Buddha in Sichuan, Emei Mountain, southern Sichuan Bamboo Sea, Huangguoshu waterfall in Guizhou, Qianhu Miao village in Xijiang River, Zhenyuan ancient city, etc. bring great convenience to the residents of Sichuan and Guizhou.

not only has great convenience for people's travel, but also promotes the economic development of Sichuan and Guizhou. Sichuan and Guizhou are both located in the central provinces of China. The convenient transportation between them can easily promote the economic cycle of the central region. In addition to the eastern cities driving the central cities, the central cities can carry out their own economic and cultural connectivity, promote the cooperation and exchange between the two regions, and constantly deepen the friendship between the two provinces. The opening of a 6031 a 6031 high-speed rail is not only for people's life, but also shows a new leap in China's high-speed rail technology. Chengdu Guiyang High Speed Railway First overcomes the complex factors of topography and topography. It climbs from Sichuan basin with an altitude of 260 meters to Yungui Plateau with an altitude of 2400 meters. After 53 large fold structures, it has 138 kilometers of crossing gas field and coal measure strata, 197 kilometers of crossing karst landform. Due to the fragile ecological environment and poor soil, it is called "funnel" in Western China. Therefore, the construction of Chengdu Guiyang high-speed railway should be carried out in the first place to ensure that the original fragile ecological environment will not be damaged. Because of the high difficulty of construction and overcoming a series of difficulties, Chengdu Guiyang high-speed railway has developed and verified China's high-speed railway technology in a very special mountain scene, and a number of world-class innovations have emerged, bringing a new level to China's high-speed railway technology.

because of the opening of Chengdu Guiyang high-speed railway, it has added a great deal of color to our country's famous construction projects. It has built the world's largest span half through steel-concrete combined basket arch bridge - Yachi River double track super major bridge; it has built the first Jinshajiang public rail dual purpose Super Major Bridge with separate bridge deck in China; and the first concrete-filled steel tube swivel arch bridge - xixihe bridge. The opening of the

Chengdu Guiyang railway is not only a new leap in China's high-speed railway technology, but also has an impact on other fields. It has formed a diversified characteristic construction with Chengdu Guiyang railway as the core, promoted the people to people exchanges between Sichuan and Guizhou, and promoted the optimization and development of other industrial structures in China.
