随着我国各城市交通的快速发展,高架桥梁建设成为其中的主要内容。高架桥梁成为缓解现代城市交通的重要存在,在越来越多的城市得到广泛的使用。因此高架桥梁的设计和施工技术也得到很大的发展,新材料与新工艺的大幅度改进促进了新结构额诞生,更改善了工程造价。高架桥梁的造价动辄上亿的投资,更需要从经济性的角度来进行方案比选和优化。鉴于此,本文对工程造价在城市高架桥梁方案比选中的应用进行了分析探讨,仅供参考。 With the rapid development of traffic in cities of our country, the construction of viaduct bridges has become one of the major contents. The viaduct has become an important part of alleviating the traffic in modern cities and is widely used in more and more cities. Therefore, the design and construction techniques of viaducts have also been greatly developed. The drastic improvements of new materials and new technologies have promoted the birth of new structures and improved the construction cost. The cost of viaduct bridges investment at hundreds of millions, but also from the economic point of view to select and optimize the program. In view of this, this article analyzes and discusses the application of engineering cost in the comparison and selection of urban viaducts, for reference only.
