Abstract
The purposes of this study is to investigate spatial structure characteristics of earthen walled fortresses based on topography, which are locational and Plane morphology, Cross sections of earthworks. Target areas of this study are 37 earthen walled fortresses which are designated as cultural properties. This study is conducted with methodologies of literature review, field investigation, investigation on topography materials and relation analyses of topography&spatial structure. The results from study on spatial structure of earthen walled fortresses are as follows. First, Earthen walled fortresses on flat topography were adjacent to water systems like rivers or streams. Plane morphology showed regular shapes. The cross section morphology presented trapezoid the most with earthworks of which outer and inner walls were built. Second, More than 70% of earthen walled fortresses on hilly topography had water system within close range of approximately 1.5km. Plane morphology was mainly with more than 73% of irregular types. Cross sections of earthworks were of morphology with more than 86% of bordered type and another type leaning against existing topography like mountains. Third, 59% of earthen walled fortresses in mountain areas had water system within their close range, which indicated that they depended on external water system less than those with hilly topography. Plane morphology was mainly with more than 67% of irregular types. Cross sections of earthworks were of monoslope method with more than 94% of bordered type and another type leaning against mountains.
본 연구의 목적은 지형에 의한 입지, 평면 및 단면 형태 등 토성의 공간구조적 특성을 규명하는 것이다. 사적이나 시도기념물로 지정된 37개소의 토성을 대상으로 문헌연구, 현장조사, 지형자료조사, 지형과 공간구조와의 관계 분석이 이루어졌다. 토성의 공간구조 연구의 결과는 다음과 같다. 첫째, 평지형 토성은 강이나 천과 같은 수계와 인접하였으며, 토성의 평면 형태는 정형적이었으며, 토루의 단면 형태는 단일경사의 사다리꼴형이 가장 많이 나타났다. 둘째, 구릉지형 토성은 1.5km이하의 근거리에 수계가 존재하는 곳이 70%이상을 차지했다. 평면 형태는 부정형이 73%이상으로 가장 많았고, 토루의 단면 형태는 테두리형과 산탁형이 86%이상을 차지하였다. 셋째, 산지형 토성은 1.5km이하의 근거리에 수계가 존재하는 곳이 59%이하로 평지형이나 구릉지형에 비해 외부 수계의존도가 낮았다. 평면 형태는 부정형이 67%이상으로 주류를 이루었으며, 토루의 단면 형태는 단일경사방식의 테두리형과 산탁형이 94%이상으로 나타났다.
