A Study of the Construction Methods for the Preservation of Important Underground Remains

In this research, the Intelligent Construction that minimizes the damage was suggested. In this case, “stress for the remains” and “direct cutting for the remains” should be avoided to preserve the underground remains. The influence of the stress for the underground remains by the execution machinery was estimated by Boussinesq formula and other geotechnical method. By this result, the limit and kind of the construction machinery were decided. Before the underground remains were excavated, the precise survey for the remains were done and recorded, usually. By these data and “Intelligent construction” which realizes precise execution is available. Based on this research, 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.
