초록

철도노반에 대한 지반조사 방법은 표준관입시험(SPT), Cone 관입시험 등이 널리 이용되고 있다. 그러나 표준관입시험은 시험장비가 크기 때문에 운행선 주변의 전철주 등에 접촉 위험이 있어 적용에 어려움이 있다. 그리고 휴대용 장비인 DCP(Dynamic Cone Penetrometer)의 경우 타격에너지가 부족하고 관입되는 Cone-rod의 강성이 부족하므로 필요 깊이까지 관입이 불가능하여 사용에 제한을 받고 있다. 이에 본 연구에서는 휴대용 장비이면서 타격에너지와 강성이 큰 Pagani Cone Test를 표준관입시험과 동일한 지반에서 시험을 실시하여 N값을 비교 분석하였다. 그 결과 Pagano Cone Test의 N값을 보정시 사질토에서 SPT의 N값의 1.48배, 점토에서 1.33배를 얻었으며, Pagani Cone Test의 N값과 표준관입시험의 N값과의 상관관계를 제안하였다.
