桥型方案的造价比较

Comparison of Different Bridge Type Cost

桥梁由于其独特的材料组成和结构构成,使其工程造价远远高于道路路基工程。特别是高速公路向山区发展后,出现了大量的桥涵构造物,使得高速公路的造价越来越高。如何合理设置桥、涵构造物,有效控制投资规模,就显得重要。影响桥梁造价的因素很较多,从设计角度而言,主要涉及到桥位选择、桥型方案、孔跨布置、技术、施工的可实施性、环境协调和造价等方面。

Because of the unique material composing and structure composing,the engineering cost of bridge is much higher than subgrade engineering.Along with the development of expressway in mountain area,lots of bridges and culverts appear,which leads to higher and higher cost of highway.How to set bridges and culverts rationally for controlling investment scale effectively is very important.There are many factors influencing bridge′s cost involving bridge location selection,bridge type scheme,span setting,technology,construction feasibility,harmony with surroundings,cost and other aspects in view of the design.
