Abstract

The recent increase of ground subsidence in Korea requires the development of technology for predicting the possibility of ground subsidence. Eighteen parameters affecting the ground subsidence for pre-excavation are classified into 6 categories considering ground types, groundwater, and external factors. Eighteen parameters consists of a table which gives ground subsidence risk ratings for pre-excavation(GSRp). Certain scores are given to these parameters after they are divided into several classes considering the importance and the credibility of parameters and the engineering judgements of the authors. Because of the difference of ground subsidence factors depending on the ground and field conditions, weighting factors for the individual factor and for the each category are multiplied. Weighting factors are calculated from citation frequencies of influencing factors. Ground subsidence risk ratings for pre-excavation can be quantified by considering the individual score of each parameter and weighting factors for the individual factor and for the each category. The suggested GSRp tables obtained from this study are expected to be used by engineers for the estimation of ground subsidence risk ratings for pre-excavation sites.

최근 국내에서 지반함몰의 발생빈도가 증가하고 있으므로 지반함몰 가능성을 사전에 예측할 수 있는 기술개발이 필요하다. 본 연구에서는 굴착 전에 지반함몰에 영향을 미치는 18개의 인자들을 지반의 종류, 지하수, 외부 인자 등을 고려하여 6가지 카테고리로 분류하였다. 18개 인자들은 지반함몰 예측을 위한 굴착 전 적용 가능한 지반함몰 위험등급 분류(GSRp) 도표를 구성하는데, 이러한 영향인자들의 중요도, 신뢰성, 저자들의 공학적 판단 등을 종합적으로 고려하여 등급을 나눈 후 점수를 부여하였다. 지반조건과 현장 상황에 따라 적용되는 지반함몰 영향인자가 다르므로 영향인자 별 가중치와 카테고리 별 가중치가 곱해지게 되는데 가중치는 영향인자들의 인용 빈도수를 기준으로 결정되었다. 지반함몰 영향인자 별점수, 인자별 가중치, 지반조건에 따라 부여되는 가중치 등을 종합하여 계산하면 굴착 전의 지반함몰 위험등급을 정량화 할 수 있다. 본 연구를 통하여 제안된 GSRp 도표는 굴착 전 현장에서 실무자들이 지반의 지반함몰 위험성을 예측하는데 활용할 수 있을 것으로 기대된다.
