Abstract

The purpose of this study is to propose a system improvement plan to prevent ground sinking accidents. To do this, follow the procedure below. First, it defines terms that are used interchangeably, such as ground subsidence and ground depression. Second, analysis of the current status and cause of ground sink, and the analysis of the correlation between rainfall and ground sink causes, derives priority management causes. Third, we propose a system improvement plan for the cause of priority management. As a result, damage to underground pipes and inadequate underground works were identified as the cause of priority management, and two system improvement plans to manage them were proposed. The results of this study can be used as basic data for improving the system for more effective prevention of underground sink in the future.

본 연구의 목적은 지반함몰 사고를 예방하기 위한 제도 개선안을 제안하는 것이다. 이를 위해 다음과 같은 수행절차를 따른다. 첫째, 지반침하 및 지반함몰 등의 혼용되어 사용되는 용어를 정의한다. 둘째, 지반함몰 사고 현황 및 원인 분석과 강우량과 지반함몰 원인간의 상관관계 분석을 실시하여 중점관리 원인을 도출한다. 셋째, 중점관리 원인에 대한 제도 개선안을 제안한다. 그 결과, 지하관로 손상과 지하공사 부실이 중점관리 원인으로 규명되었으며, 이를 관리할 두 가지의 제도 개선안을 제시하였다. 본 연구의 결과는 향후 보다 실효성 있는 지하함몰 예방을 위한 제도개선의 기초자료로 활용될 수 있다.
