【摘要】：公路工程建设是国民经济发展的重要影响因素,也是基础设施建设的重要组成部分。我国每年都有大量资金投入到公路建设中,在建设前期的投资估算,是对项目的决策,以及工程的可行性研究的关键环节。长期以来,相关领域的学者对公路工程的投资估算进行了诸多研究,取得了很多成果,但仍有不足。这是由于其具有的建设周期长、环境复杂多变、影响因素众多等特点使得公路工程造价具有高度的不确定性,这为我们工程造价投资估算带来了巨大的困难,研究和探索出一套动态的公路工程造价估测方法,具有重要的实际意义和工程参考价值。本文针对公路工程规划阶段投资估测需要,首先回顾了当前国内外公路造价投资估算的研究现状及发展趋势,通过对公路工程的造价构成分析,得出建安费是整个公路工程项目估算的决定性因素。然后研究构建了公路工程造价估测指标体系,基于历史数据的调查整理,利用MySQL数据库管理系统平台建立了公路造价案例库,服务于案例推理的工作流程,提出了基于案例推理的公路投资估测系统,并通过工程实例验证了该系统的有效性,具有一定的工程应用价值与借鉴作用。
[Abstract]:Highway construction is not only an important factor of national economic development, but also an important part of infrastructure construction. Every year, a large number of funds are invested in highway construction in China. The investment estimation in the early stage of construction is the key link of the project decision and the feasibility study of the project. For a long time, scholars in related fields have made a lot of research on the investment estimation of highway engineering, and achieved a lot of results, but there are still some shortcomings. This is because of its long construction cycle, complex environment, numerous factors and other characteristics of highway engineering cost has a high degree of uncertainty, which has brought great difficulties for our project cost investment estimation. It is of great practical significance and engineering reference value to study and explore a set of dynamic estimation methods of highway engineering cost. In view of the need of investment estimation in highway engineering planning stage, this paper first reviews the current research status and development trend of highway cost investment estimation at home and abroad, and analyzes the cost structure of highway engineering. It is concluded that the construction and safety fee is the decisive factor in the estimation of the whole highway project. Then it studies and constructs the index system of highway engineering cost estimation, based on the investigation and arrangement of historical data, establishes the highway cost case base by using MySQL database management system platform, which serves the work flow of case-based reasoning. The highway investment estimation system based on case-based reasoning is put forward, and the effectiveness of the system is verified by an engineering example, which has certain engineering application value and reference value.
