Abstract

Purpose: This study analyzes and studies the characteristics of the Jeju area and uses them as basic data such as construction method design in the future development project. Method: Based on the ground survey data of the construction conducted in Jeju, the depth, relative density, N value, function state, color tone, groundwater level, and compressive strength were analyzed and studied. Result: Studies show that Jeju has columnar joints consisting of ancient volcanic activity and rapid cooling by nearby seawater, thick sand layers found on the coast, and clinker layers and Seogwipo layers formed by Mercury volcanic activity. Conclusion: It is hoped that it will be used as data for selecting basic design and basic construction method by understanding the special ground form of Jeju area and reflecting its characteristics well when designing construction.

연구목적: 본 연구에서는 제주 지역 지반의 특성을 분석하여 연구함으로써 향후 개발사업 진행시 공법 설계등의 기초자료로 활용한다. 연구방법: 제주 지역에서 진행된 공사의 지반조사 데이터를 기반으로 심도, 상대밀도, N치, 함수상태, 색조, 지하수위, 압축강도를 분석하고 연구하였다. 연구결과: 본 연구로부터 제주지역이 고대부터 진행된 화산활동과 인근의 해수에 의한 급속한 냉각으로 이루어진 주상절리와 해안부에서 두텁게 발견된 모래층, 그리고 수성화산활동에 의해 형성된 클링커층 및 서귀포층이 존재함을 알 수 있었다. 결론: 제주지역의 특수한 지반 형태를 이해하고 공사 설계시 그 특성을 잘 반영하여 기초 설계 및 기초 공법 선정의 자료로 쓰여지길 기대한다.
