| The quota is the basis for determining the project cost and compiling the fund plan.In the process of construction and development of domestic landscape engineering projects,the construction technology is sound,and the research of project cost is also indispensable.At present,in the design estimate,construction drawing budget,completion settlement and other project cost compilation and audit work of the landscape steel cross-line bridge,most of the reference road bridge and other industry quotas,and not suitable for the landscape steel cross-line bridge budget quota.It is of great significance to study the quota measurement for reasonably controlling the cost of landscape steel cross-line bridge,issuing scientific and reasonable quota standard,improving and perfecting the market system of steel box girder engineering and perfecting the market mechanism of industry,so it is an important content to study the quota measurement of landscape steel cross-line bridge.In order to solve the problems of steel box girder engineering installation quota level and project measurement and settlement,the quota consumption of steel box girder has been studied by using the method of scientific research.The calculation model of steel box girder quota measurement consumption has been constructed by using the theory of Laida criterion(3σ criterion),grey prediction model GM(1,1)and quadratic average method according to the actual engineering equipment.The relative error of the model is 7～8 percent and the model is reliable.According to the principle and method of compiling the quota of steel structure engineering in Hebei Province,the installation of steel box girder and the determination of the quota of temporary support has been formed.It not only provides an effective basis for the relevant audit departments in the process of audit,but also has reference significance for the compilation or updating of quotas in other industries.Figure5;Table29;Reference50... |
