Abstract

Most of the industrial complexes and housing complexes in Busan and Gyeongnam were constructed by developing mountainous areas, except for some landfill areas. During the development process, the surplus soil for site development was mainly used as the embankment material. In the field, however, even if the material of the material changes during the embankment work for site development, for convenience reasons such as construction period and site conditions, the material property test and compaction test are not additionally conducted for the embankment material, and quality control is conducted. In this study, physical property tests and compaction tests were conducted on surplus soils in mountainous areas in Busan, GyungNam Province and then regression analysis was performed on the data. In addition, a comparative analysis was conducted along with existing studies in Korea. The surplus soils at the sites in Busan and Gyeongnam were mainly weathered soils of granites, and were classified into clayey sand (SC) and silty sand (SM). As a result of regression analysis of the compaction characteristics according to the content of coarse and fine soils, the correlation between them was very high. Using the relational formula as a result of this study, it will be very useful for compaction management of the surplus soils in the field.

부산 및 경남지역의 산업단지 및 주택단지 조성은 일부 매립 지역을 제외한 대부분이 산지를 개발하여 형성되었다. 단지 개발과정에서 부지조성을 위한 산지 현장 발생토를 성토재료로 주로 사용하고 있다. 하지만 현장에서는 부지조성을 위한 성토작업 시 재료의 재질이 변화하여도 시공기간 및 현장여건 등의 편의상의 이유로 성토 재료에 대하여 물성시험 및 다짐시험을 추가적으로 실시하지 않고 품질관리를 하고 있는 실정이다. 본 연구에서는 부산 및 경남지역 산지 현장 발생토에 대한 물성시험 및 다짐시험을 실시한 후 회귀분석을 실시하였다. 그리고 국내의 기존연구와 비교 분석하였다. 부산 및 경남지역 현장 발생토는 주로 화강암류의 풍화토로서 점토질모래(SC) 및 실트질모래(SM)으로 분류되며, 조립토 및 세립토의 함유량에 따른 다짐특성을 회귀분석한 결과 상관성이 매우 높은 것으로 나타나 금 번 연구결과 관계식을 활용하면 현장 발생토의 다짐관리 시 매우 유용하게 활용될 수 있을 것이다.
