| Ancient underground remains are important historic memorials for the nation and should be preserved for the future research. But sometime infrastructures (for example, road, park, and so on) constructed on these areas.In this research, the construction methods that minimize the damage were suggested. Especially, “stress for the remains” and “direct cutting for the remains” should be avoided to preserve the underground remains.For these cases, “Intelligent construction” is very useful. Usually underground remains were excavated beforehand, and then, the precise results of the survey for the remains were recorded. By these data and “Intelligent construction”, precise execution is available.Based on this study, the execution was done at the Asuka-Nara Palace Site Historical National Government Park (Nara Palace Site), that is one of Japan's representative historical and cultural legacies and a Special Historic Site as well as being a constituent part of the World Heritage site "Historic Monuments of Ancient Nara." Although the execution was done above the underground remains, they were preserved successfully. |
