This study reviewed cases in which the archaeological construction hypotheses of excavated sites, such as earthen walls, embankments, and site formations, were analyzed using civil engineering methods. In order to interpret the characteristics of the sites presented from the archaeological point of view, ground investigations, soil tests, and model tests were conducted, and the construction scenarios of the sites were verified using computer modeling techniques.
The result of an archaeological investigation that the size of the east wall of Pungnaptoseong in Seoul was enlarged through the process of extension is engineering probable, and the point of view that the wooden fence confirmed at the upper part of the wall in the Haman Gayari site was a defensive device is also a factor to be considered meaningfully. The stone layer confirmed at the lower part of the central girder of Gimje Byeokgolje can reduce the heaving of the ground under the water gate, and the prototypes of the Haman Gayari embankment and the Ulsan Yaksa-dong embankment were derived from the slope stability rate and water infiltration analysis. Sedimentary layer of plant organisms, from which wooden tablets were intensively excavated from Seongsansanseong Fortress in Haman, must have functioned as a drainage material to keep the water level inside the surface below a certain level after the fortress wall was completed. The construction method of site formation at Gongsanseong Fortress is an engineering way to prevent collapse due to slope and safely construct it.
In order to analyze the construction hypothesis of such sites engineeringly, it is most important to improve the reliability of archaeological data. Efforts are needed to build a research model for the analysis of the remains by participating in the engineering field from the planning stage of the excavation investigation.
