"China span" is the glory of China Railway Bridge in 70 years

In the vast land of the motherland, there are many railways and high-speed rail... In the past 70 years, the total mileage of railway business in China has increased by more than 5 times, and remarkable achievements have been made in the scale of railway network and the speed of trains per hour. Not only "China's speed", but also the railway bridge that plays the role of "through the needle, connecting to the Internet" has become a national card, and "China's span" has been praised by the world time and again. (people's railway daily) since the founding of the people's Republic of China, with the unremitting efforts of generations of railway people, one railway has roared, one bridge has connected one railway, crossed deep mountains and canyons, connected the north and south of the river, and become the poverty alleviation Road, development road and link to the world. China Railway Bridge not only represents the highest level of railway transportation infrastructure construction, but also becomes a beautiful card to show the great development achievements and comprehensive national strength of China Railway in the past 70 years.

China's vast and long-term railway network needs the support of many railway bridges. However, the railway bridge has a large load, a large impact force and a large traffic density, which requires a high standard of resistance to natural disasters, especially the structure requires a certain vertical and horizontal stiffness and dynamic performance. At present, China railway bridge construction technology has made a lot of achievements, its design and construction level has also been the world's attention. Especially in the rapid development period of China's high-speed railway, the achievements of railway bridge technology and innovation are obvious to all.

railway bridge builders take the perseverance of dripping water through stone and long time as their contribution, and the pioneering spirit of pioneering innovation and daring to be the first, which not only promotes the development of China's transportation industry, but also greatly helps the progress of the world's bridge industry!

when the word "people" is deeply engraved on the name of the new China Railway, when the railway people take "serving the people" as their eternal pursuit, and let the people enjoy the best way to become the most moving movement in the railway people's 70 year grand symphony. In the past 70 years, from the establishment of the Institute, striving to catch up with the world and leading the world, railway people have been down-to-earth, promoting the design, construction and construction of railway bridges to keep up with the trend of the times, and the construction process is becoming more and more scientific, modern and intelligent. The

bridge is the extension of the road. According to the medium and long term railway network planning, the scale of China's railway network will reach 150000 km by 2020, among which the mileage of high-speed railway will reach 30000 km, forming the "eight vertical and eight horizontal" high-speed railway network. With the rapid extension of high-speed railway, high-speed railway bridges will be better innovative development. In the future, there are also cross sea channels such as Qiongzhou Strait channel and Bohai Bay channel that need to be built, and mountains in the West need to be crossed. China's long-span high-speed railway bridges should continue to adhere to innovation driven, demand led, serve the sustainable development of national economy and society, and serve the "belt and road" and other national strategies.

in the past 70 years, railway people have made unremitting efforts to explore new maintenance methods, so that railway bridges can better benefit the people. Reading the relevant stories, you can appreciate the great power of the Republic, "China span", and build a brilliant railway development process of new China. Touch the development temperature of 70 years, and more sense the strength of railway people's livelihood. (Yao Hong)
