【摘要】：公路改建工程项目不但具有投资额大、回收期长、涉及范围广的特点,还会对社会经济产生长远而重要的影响。为确保改建项目以最合理的技术及最小的投资取得最佳的社会经济效益,避免投资决策失误,有效降低项目建设风险,进行公路改建项目的技术方案比选及其经济评价研究具有十分重要的意义。本论文以S319省道宁波江北段公路提升改建工程为研究实例,通过对项目影响区域的社会经济和交通运输状况的现状进行前期调查,结合公路专业与项目管理专业的理论和实践经验对数据进行了系统的处理,分析了道路交通现状及远景发展需求的分析,通过预测交通流量,确定论证了技术标准、建设规模；对工程的关键分项工程提出技术方案并进行比选,确定最佳的提升改建方案,然后对其进行经济评价,最终论证方案的合理性和经济性。论文提出,通过对改建道路平、纵线形拟合,横断面、软土地基处理、路面结构、桥梁改建方案的技术、经济比选,可以有效的提高项目的技术可行性与经济效益。因依托项目的特殊性,研究结论未必具有广泛的适用性,但对同类省道公路的提升改建具有一定的参考价值。
[Abstract]:Highway reconstruction project not only has the characteristics of large investment, long payback period and wide range, but also has a long-term and important impact on social economy. In order to ensure that the reconstruction project can obtain the best social and economic benefits with the most reasonable technology and minimum investment, avoid the mistake of investment decision, and effectively reduce the project construction risk, It is of great significance to compare and select the technical scheme of highway reconstruction project and to study its economic evaluation. Taking the highway upgrading and rebuilding project of Ningbo Jiangbei section of S319 Provincial Highway as an example, this paper makes a preliminary investigation on the current situation of social economy and transportation in the area affected by the project. Based on the theoretical and practical experience of highway specialty and project management specialty, this paper systematically deals with the data, analyzes the present situation of road traffic and the demand for future development, and determines the technical standard and construction scale by forecasting traffic flow. The technical scheme of the key sub-project of the project is put forward and compared and selected to determine the best scheme of lifting and rebuilding. Then the economic evaluation is carried out to demonstrate the rationality and economy of the scheme. The paper puts forward that the technical feasibility and economic benefit of the project can be improved effectively by comparing the technology and economy of the reconstruction road plane, longitudinal line fitting, cross section, soft soil foundation treatment, pavement structure and bridge reconstruction scheme. Because of the particularity of the project, the conclusion of the study may not have wide applicability, but it has certain reference value for the upgrading and rebuilding of the similar provincial highway.
