阐述了高速公路扩建工程可持续发展概念的内涵和外延。针对扩建工程的可持续发展战略目标，建立可持续发展的目标体系，将高速公路扩建工程作为项目群系统研究，构建了扩建项目全寿命周期集成化管理系统。围绕集成化管理的三维坐标体系，解释了扩建工程全寿命周期的涵义，分析扩建工程的项目群特征及“扩建—运营—交通管理”一体化组织结构。建立了高速公路扩建工程全寿命周期信息结构矩阵和信息管理系统。采用可持续性晴雨表建立高速公路扩建工程可持续发展的评价模型。总结了基于可持续发展的高速公路扩建工程的建设管理能够为后续工程建设和行业发展提供的启示。

The paper expounded the extension and connotation of sustainable development conception of expressway extension project. In allusion to the stratagem objective of sustainable development, the objective system of sustainable development was constructed and expressway extension project was studied as programme system. The paper constructed the life-cycle integrated management system of expressway extension project. Around the three-dimensional coordinate system of integrated management the meaning of expressway extension project life-cycle was explained. The programme characteristics were analyzed and an incorporate organizational structure of "extension—operation—traffic management"  was built. The paper built information structure matrix and information management system of expressway extension project life-cycle and used weatherglass to build an evaluation model of sustainable development. At last, the inspirer was summarized which the research on expressway extension project construction management based on the theory of sustainable development can offer to the construction of engineering after and the development of industry.
