— — Chinese bridges up to half a century of history
Humen bridge is a bridge-building history stages of progress.
Minister of science and Technology Xu Guanhua inspected in August of this year the construction site of the Sutong bridge in China bridge construction is China's independent innovation of a banner.
Under construction Sutong bridge.
"A bridge to fly North-South, great variable thoroughfare", 1957, 15 October, connect both sides of the North and South of the Yangtze River for the first block, bridge---Wuhan was opened to traffic, over thousands of years there is a boat without great Yangtze River Bridge, however, it is regrettable that this landmark significance of bridges, or the former Soviet Union help China.
As long as half a century later, the bridge across the Yangtze River in China has 48 seats, prospered China Bridge industry, has jumped to the world's largest bridge market.
Now, every year the number of bridges need to build up to a thousand, and one of the larger bridges also has more than 100 seats. It is particularly important, in bridge engineering efforts, China has achieved bridge border 100 per cent independent manufacturing, a path of independent development.However, for purposes of Chinese bridge border, everything is just beginning.
International Association for bridge and structural engineering, Vice President, academician Xiang haifan not without fear and said, great power from bridge to bridge power, China very objective some distance to go.Nanjing Yangtze River Bridge, the first step
In Xiang haifan it appears that China bridge in the histo
ry of the first milestone was in 1958, Nanjing Yangtze River Bridge open, China's independent building bridges. Although the bridge has a length of only 100 meters, is the equivalent of the "first step".While most worthy celebration of the day, it was 1991, Shanghai nanpu bridge's completion.
"At that time the project nearly got Japan bridge border away, thanks to the then President of Tongji University Liguohao force main building designed by us. " Xiang haifan feeling that it is this block, 400 meters of cable-stayed bridge project, changed China bridge border development trajectory. "When completed, many local experts to come and learn from, are very heartened, they say, you can do, we can do!" China Bridge community independent tide to rise.The "first step" effect is undisputed, item state sail told reporters that now Southeast Asia countries, in bridge-building aspects still relies heavily on foreign technology, it is this "first step" did not go out.
"Independence" is not equal to "innovation"
"It is important to note that the size is not something to be proud, independent cannot stand still.
" Xiang haifan seriously pointed out that China's bridge territories while the" clear ", but the comparison is being made, or" people in 30 years ago had already done. "" So I've been saying, now publicity bridge, so that it spans much, how many steel quantity, evaluated several "best", but these cannot describe China bridge technology has been developed to the extent of the world's leading, not innovation, because, to use outdated technology, as do the new bridge. "" Now that most of our technological innovation is the introduction of digestion and absorption of innovation on the basis of, just a kind of learning and tracking phase of low levels of innovative activity. "Xiang haifan pointed out that the gap between China's bridge construction, and currently focuses on innovation, quality and durability problems and aesthetic consideration paid enough attention to, etc. "Only in cutting-edge technical difficulty to compete with foreign counterparts, and lead through innovation, breakthrough to achieve true beyond. ”■ Character dialogue
"The world bridge power needed 20 years"
Dialogue with the International Association for bridge and structural engineering, Vice President, academician Xiang haifan
A sadderbut a
Reporter: the world's most advanced bridge industry is what countries? current distance world bridge power long distance?
Xiang haifan: a reporter asked me that now call the world bridge border "top ten", my answer is: barely considered.
Now the old bridge in the world is a powerful country of Germany, France, UK, USA, Switzerland, Japan and Denmark rookie has, since the latter belongs to the island, the need to construct part of the cross-harbour, greatly improving their technical level, the other bridges in several countries, and China's level counterparts, such as Italy, Canada, Australia and so on.
The so-called "knowing that victory is strong," objectively speaking, our country is moving into the bridge's great power, but also not fully considered bridge
Beam power. It is worth for sure is that we distance in the early years of world advanced level at least 30 years or so have up to a distance of 10 years of distance, of course, the world's advanced level nor is stationary, we need to make further efforts to catch up.Reporter: since there is less than the level of domestic bridge, then why can't break into the overseas Chinese bridge border bridge market?
Xiang haifan: I give you an example, Jiangyin construction, $ 10 billion, half of independent building to, for various reasons, to the United Kingdom bridge construction contracting sect
or. At that time, the United Kingdom company funding is 9000 pounds, but their artificial was expensive, inadequate funding, and therefore they all contracted out to the construction of bridge company in China.As a result, the Jiangyin completed, United Kingdom company funds left $ 400 million Yuan, and they earn back.
With this lesson, Jiangsu reengineering bridge, United Kingdom to bridge community for construction qualifications, but local governments do not have them.However, we concluded that the four million flowers have the value so we paid the school fees, a United Kingdom bridge border rigorous management and many other experiences, later foreigners but also know: Chinese people is very clever, you'll learn it once.
Talents decide innovation
Reporter: do you like, change the current lack of innovation in China's bridge border situations should be how to proceed?
Xiang haifan: must recognize that building a new bridge is not equal to innovation.
Building a bridge in foreign countries, only need tens of thousands of individuals, we frequently, though artificial cheap, but this is what I say "using backward technology makes new bridge". No innovation, or bridge.Causes of insufficient innovation or Chinese bridge border personnel competence is not enough.
The point I and the Chinese Academy of Sciences, former Dean ZHOU Guangzhao, talents to best foster the child's curiosity from, imagination, to encourage originality, change the present form of education is imperative.
Innovation is not a bit of time to solve, need for several generations.Future focus is on the West Coast,
Xiang haifan: now on the Yangtze River Bridge are almost all c
onstruction, the next step should be to focus on the coast and the West, are difficult to bridge building. For example, the Zhoushan Islands along the coast, there is an urgent need to build bridges, because their seafood was previously available only to transport by boat; and the construction of Expressway West to the mountains to open tunnels, and open the tunnel after the need to bridge to support.This version of the author: Nanfang Dushi Bao, reporter Inn days
