清单计价模式下的公路桥梁工程总体设计质量控制

Quality Control of Overall Design of Highway and Bridge Engineering Under List Valuation Mode

基于清单计价模式,以贵州某高速公路桥梁工程项目为研究对象,对公路桥梁工程总体设计质量控制进行了分析研究。通过将该高速公路上的桥梁工程上部分和下部分结构选用、施工工艺方式、景观景象等作为对比分析的对象,并以清单计算价格模式进行最优经济组合,主要是从价格对桥梁墩高、跨径等数据进行估算。分析表明:墩高为15. 5～20. 5 m时采用25. 5 m小箱梁;墩高在小于15. 5 m时采用20. 5 m小箱梁; 20. 5～29. 5 m墩高时,从清单计价方式中可发现,选用29. 5 m的小箱梁为最佳跨径的组合。在工程量清单计价模式下进行材料、人工、设备使用情况分析,及时完成工程并确保工程的质量。

Based on the bill valuation model,taking a highway bridge project in Guizhou as the research object,this paper analyzes and studies the quality control of the overall design of highway bridge project.By comparing and analyzing the structure selection of the upper part and the lower part of the bridge project on the expressway,the construction technology and the landscape scene,the optimal economic combination is carried out by using the list price model,mainly estimating the pier height,span and other data from the price.The analysis shows that when the pier height is 15.5~20.5 m,25.5 m small box girder,20.5 M small box girder and 20.5~29.5 m pier height are used when the pier height is less than 15.5 m,and 29.5 m small box girder is the best combination of span.Analyze the use of materials,labor and equipment under the bill of quantities valuation mode and complete the project in time to ensure the quality of the project.
