山岭重丘区公路20m以下空心板梁集中预制安装的利与弊

Discussion on advantages and disadvantages of concentrated precast and erection for voided slab beams with less than 20 meters in the heavy rolling area

建设项目不仅要满足使用功能,其经济评价、社会评价、环境评价(环境污染、周边生态平衡、国民经济效益)、综合评价等也是功能评价的重要指标。文章针对工程实例,并根据价值工程理论,对山岭重丘区公路20 m以下空心板梁采用"集中预制安装"方案的可行性、成本、效果总评价方面进行了分析。

The construction projects need to meet the requirements of working function, while the important criteria for functional evaluation are the economic evaluation, the social evaluation, the environmental evaluation （ pollution, ecological balance around project, national economic benefit）, and comprehensive evaluation, etc. Based on the project practice and the theory of value engineering, this article analyzes the feasibility, the cost, the general effectiveness on the plan for concentrated precast and erection for voided slab beams of highway bridges in heavy rolling area, with a span of less than 20 meters in length in heavy roll- ing area.
