对两位桥梁专家的采访给了我们这样的认识:关于造桥,老课题是技术攻关,新课题是可持续发展。道理就好比老专家吃了螃蟹,而新专家不但要吃螃蟹,还不能留下蟹爪蟹壳来污染环境。回头看一下,从那些使天堑变通途的实用桥梁到经济的桥梁再到美观的桥梁,以及现在我们希望的没有残骸的环保桥梁,我们对桥的要求的确越来越高。专家们也不再埋头造桥,而是抬眼看四周,看未来。这是一个有关永续发展的神圣而有趣的话题:柴要烧,青山也要留。读了两篇采访不由得令人思考关于造福,关于进步与文明,关于眼前利益与长远利益。其实,眼前很短的利益曾经也很长。好在有了发展的眼光,我们的思考就有了支点;不同时代的桥承载不同的需求,不同时代的造桥人有不同的使命,我们更应关注的是一种精神,一种责任感,这是最重要的。——编者 The interview with the two bridge experts gave us such a recognition: Regarding bridge construction, the old task is to tackle key problems and the new task is to achieve sustainable development. The truth is like the old experts ate crabs, while the new experts not only eat crabs, crab claw crab shells can not be left to pollute the environment. Looking back, from the pragmatic bridges that make the natural moat a thoroughfare to the economic bridge to the beautiful bridge, and the environmentally-friendly bridge that we now hope for without any wreckage, the demand on the bridge is indeed getting higher and higher. Experts are no longer buried in the bridge, but looked up and looked around to see the future. This is a sacred and interesting topic about sustainable development: firewood is to be burned and green hills are to be kept. Reading two interviews can not help thinking about the benefits, on progress and civilization, on the immediate and long-term interests. In fact, the immediate benefits have been very long. Fortunately, with the development of vision, our thinking has a fulcrum; bridge of different ages to carry different needs, different generations of bridges have a different mission, we should pay more attention to the spirit of a sense of responsibility, This is the most important. --editor
