부소산성 성벽의 변천과정 연구

Abstract

Busosanseong Fortress located in central northern part of Sabi which is the last capital of Baekje Dynasty is important to understand the history of the Baekje Sabi period. In this article, the transition process of rampart in Busosan mountain over time was reviewed upon classifying the investigation periods of the rampart by the step and summarizing the similarities among the periods. The result revealed that some rules had been applied by the step when constructing the rampart. Rampart 1 surrounding over Busosan mountain can be divided by four steps. In Step 1 as the first rampart construction in the mountain, neat rammed earth and 130cm apart wooden poles on average are found. Within the rampart together with Naewhando, the drainage is circled side by side with the rampart. In Step 2, stones or clay roof tiles are supplemented to the rampart of Step 1. The interval between wooden poles seems to tend to widen a little bit compared to that in Step 1. From Step 3 in the unified Silla period, the unorganized rampart with rammed earth is constructed, and stonework is added in the lower body of external wall in the section overlapped with Rampart 3 in the mountain. After Step 3, mounding and covering in Goryeo and Joseon dynasties are found where additional wall was constructed once again in the unified Silla and the wall was overlapped with Rampart 4 in the mountain. Rampart 2 in Busosan mountain surrounding the peak area of Sajaroo passed three steps of the construction. In the step 1, rampart with rammed earth was constructed but not a neat way compared to the rammed earth in Rampart 1. In the step 2, lower slope of this rampart was cut and stone rampart was constructed. In the step 3, the stone poles were added in front of the existing rampart, which did not pile the wall as had done in the step 2 nor use rectangular stones. In step 1 of Rampart 3 surrounding plane area of the southern mountain, rampart with rammed earth was constructed as seen in the step 3 of Rampart 1 and lower part of the external wall was closed with stone poles. In the step 2 mainly found in the northern and eastern parts of the military warehouse area, the rampart was supplemented with mounding by the upper part of the existing rampart or rammed earth again. Step 3 was the covered layer in Goryeo and Joseon dynasties. In Rampart 3 over the military warehouse area, the rampart was used with mounding on the upper part of the wall in the sections with the existing rampart of the prior periods and the rampart was constructed with stone poles externally and rammed earth internally in the sections without the existing rampart.
