Abstract

In recent years, ground subsidence, excavation collapse, earth retaining wall failure, and slope slip have occurred at construction sites as symptoms of the failures of multifactorial systems resulting from a complex interplay of factors, including uncertainty in the ground conditions, simplification of design assumptions, stress redistribution during construction, and inadequate measurement and management systems. However, domestic accident investigation systems currently focus on identifying administrative liability, leading to a lack of quantitative verification and standardized construction forensic systems. In this context, the present study proposes a standard forensic investigation model based on geology and geotechnical engineering that integrates quantitative stability assessment, measurement-based back-analysis, and a hierarchical analysis of root causes. The aim is to transition to a scientific and engineering analysis system that includes reproducibility and verification procedures compliant with international quality standards for the recalculation of safety factors and sensitivity analysis between parameters, considering the ground characteristics.

최근 건설현장의 지반침하와 굴착 붕괴 및 흙막이 파괴 그리고 사면활동 등은 지반 조건의 불확실성과 설계 가정의 단순화 및 시공 중 응력 재분포, 계측·관리체계 미흡 등과 같이 복합적으로 작용하는 다요인적 시스템의 실패 형태로 나타난다. 그러나 국내 사고조사체계는 행정적 책임 규명 중심으로 운영되어 정량적 검증과 표준화된 건설 포렌식 체계가 부족한 실정이다. 이에 본 연구는 정량적 안정성 평가와 계측 기반의 역해석 및 근본원인(Root Cause)의 계층 분석을 통합한 지질 및 지반공학을 기반한 포렌식 조사 표준 모델을 제안하여 안전율 재산정 및 지반특성을 반영한 매개변수간 민감도 분석은 국제 품질 기준에 정합하는 재현성과 검증 절차를 포함하여 과학적, 공학적 분석 체계로 전환하고자 한다.
