Abstract
大型的土木建築技術正在轉變。現在看到橋樑工程結構的輕盈程度，我們會感到驚奇。儘管橋樑的性能越來越高，但建橋所使用的材料從數量和重量上有越來越少的趨勢。之所以可以做到這樣，一部份原因是建橋的原則發生了變化，各種材料的使用都得到了優化，因此減少了材料的用量，橋樑的設計思路也不斷創新。除此之外，工程建設中還出現了一些新的限制，比如建橋時要考慮對環境的影響因素，尤其是橋樑在建設過程當中和投入使用之後，都要更好地與當地的環境結合在一起，這方面的規定更加嚴格，人們對橋樑在建設和使用過程中可能出現的風險，從觀念也發生了一些變化。由此而產生的新標準，導致產生了「現代」的橋樑文化。莫城的高架橋就是一個現代橋樑的典型例子。
Techniques for major civil engineering structures are changing. The lightening of structures is surprising: the mass and quantity of material is tending to diminish, despite still high performances. This is mainly due to a change in philosophy, where the use of each material is optimised, enabling the quantity to be reduced, thus leading to renewed inventiveness in design. To this can be added new constraints, such as taking into account environmental factors in particular on sites, admission rules to reinforced sites, and changing notions of risk and responsibility both for the site and the structure in service. All these factors are leading to a modern culture for civil engineering structures, as was typically the case for the Meaux viaduct in France.
