20世纪桥梁工程发展历程回顾及展望

Development and Prospects of Bridge Engineering in 20th Century

从学科发展、建设规模及速度、墩台和基础工程、设计风格等方面回顾了本世纪桥梁工程的发展历程，经分析认为本世纪桥梁工程得以迅猛发展是源于材料革新、电子计算机技术、预应力思想、自架设体系思想、桥梁设计竞赛机制、施工管理体制等方面。对下一世纪桥梁工程发展进行了预测并对超级跨海工程的前期工作提出了建议。

In this paper,development of bridge engineering in the 20th century is reviewed.Then,developing tend of the engineering in the coming century is predicated for.Finally,some proposals on building of super long span bridges are given out.
