This study aims that postwar civil engineering projects, that is large scale infrastructures, are evaluated fairly throughout the future. Though evaluations of the civil engineering heritages have been carried out until now, these facilities have been limited before 1945. This study is, taking up the large scale infrastructures after 1945. The documents which clarified the planning process were collected and saved, and the interview surveys for the interest parties who exists were carried out. Intended infrastructures are Seikan Tunnel, Otaru Canal, Hachirougata reclamation, Tadami River electric power development, Metropolitan Expressway, Meishin Expressway, Trans-Tokyo Bay Highway, Narita Airport, Tokaido Shinkansen, Honshu-Shikoku bridges, Kanmon Bridge and Tunnel. Research partakers all over Japan have studied each end.Main accomplishments by this study are as follows.1) Social environment changes were coordinated in the time of planning and afterwards. 2) The following were shown in evaluation of large scale social infrastructures : Not only economical index but also civil engineering historical evaluation is important.3) For planning and realization of the large scale infrastructure, it was shown that reliable consensus building process was necessary.

本研究旨在对战后大型基础设施这一战后土木工程项目进行全面、公正的评价。虽然到目前为止已经对土木工程遗产进行了评估，但这些设施在1945年之前一直是有限的。本文的研究对象是1945年后的大型基础设施。收集和保存了澄清规划过程的文件，并对存在的利益相关者进行了访谈调查。拟建的基础设施包括青冈隧道、小田运河、八路填海、多美河电力开发、都会高速公路、美新高速公路、跨东京湾高速公路、成田机场、东海道新干线、本州-四国大桥、关门大桥和隧道。日本各地的研究人员对每一端进行了研究。本研究的主要成果如下：1)社会环境变化在规划时和规划后协调一致。2)在大型社会基础设施的评价中，不仅经济指标重要，土木工程历史评价也很重要。3)对于大型基础设施的规划和实施，可靠的共识建立过程是必要的。
