최근 사회 문제로 관심이 높은 도심지 지반 함몰은 주로 지하시설물의 손상으로 인해 발생한다. 그러나, 지하에 매설된 시설물들은 직접 눈으로 상태를 확인하는 것이 매우 어렵다. 따라서, 본 논문에서는 지반 함몰을 예방하기 위해 AIoT 기술과 공간지도를 활용한 지하시설물 및 지반의 안전도 평가 방안과 결과에 대해 논의한다. AIoT 기술은 지하시설물과 지반의 현재 상태에 대한 직접 평가를 위해 사용하며, 공간지도는 지하시설물의 속성 정보를 활용한 간접 평가를 위해 사용한다. 이와 같은 방식을 적용하여 지하시설물에 대한 상태 등급 지도를 만들어 가시화하여 위험도가 높은 지하시설물의 유지 보수 우선 순위를 높이고, 지하공간에 대한 위험 지도를 생성하여 위험 지역에 대한 굴착공사 후 좀 더 주의 깊은 복구를 유도하여 지반 함몰을 예방할 수 있는 기초자료를 제공한다.
