Research On Cost Indicators Of Typical Structures Of Expressway Of Mountain Area

With the development of society and economy, the expressway of mountain area of China enters a rapid development period. However, the structures of expressway of mountain area account for a big proportion and have two important characteristics of big project amounts and high cost, such as bridge, tunnel, intercommunication, and so on, and the project alters frequently, the unsteady range of cost of construction is big, controlling construction cost is very difficult, but the indicator system of cost of construction have not been developed so far. For this purpose, this article has conducted the research on construction cost indicator system's construction of typical structures of expressway of mountain area, and has carried on the discussion to its application situation.This article contrasts the characteristics of project and cost of typical structures between the expressway of mountain area and the expressway of plain area, refers "four principles" of selecting typical projects, utilizes comparison analytic method and the system analytic method comprehensively, and selects bridge, tunnel and intercommunication as the object of study; Proposes the construction of "the double indicators" system, which unifies The resilience and the economic indicator in the foundations of the overall target and the sub-item target, and introduces Construction space to indicator system; Uses the methods of four uniform, analysis the body of study in consumption of Engineering material, construction cost, construction craft, and has developed indicator systems of construction cost of bridge, tunnel and intercommunication separately; Points out the order of "completion final accountsâ†'two stage designsâ†'initially suppose the stage" that should been followed when selects materials, and the "four aspects" that using in Reorganizes the firsthand information; Finally, calculate and Analysis the main Cost indicator using the expressway of "Yunwu" of Guangdong Province, a typical expressway of mountain area, and draws some rich regular conclusion。...
