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.

本研究的目的是战后土木工程项目，即大型基础设施，在整个未来的公平评估。虽然对土木工程遗产的评估一直在进行，但这些设施在1945年之前是有限的。本文研究的是1945年以后的大规模基础设施建设。收集和保存了澄清规划过程的文件，并对现有的利益方进行了访谈调查。计划建设的基础设施包括青函隧道、小樽运河、八浪形填海、忠见川电力开发、首都高速公路、名神高速公路、跨东京湾公路、成田机场、东海道新干线、本州四国大桥、关门大桥和隧道。本研究的主要成果如下：1）在规划期间和规划之后，协调了社会环境的变化。2)在大型社会基础设施的评价中，不仅要考虑经济指标，还要考虑土木工程的历史评价。3）对于大型基础设施的规划和实现，可靠的共识建立过程是必要的。
