Technical Standard Analysis and Optimal Monitoring Technology to Prevent Ground Subsidence

Abstract

As ground subsidence has recently been gaining public attention, the government (the Ministry of Land, Infrastructure and Transport) as well as local autonomous bodies have recommended preemptive monitoring and have announced a variety of preventive measures against this catastrophic phenomenon. Furthermore, risk factors associated with ground subsidence were identified in a bid to raise awareness regarding the importance of developing preemptive and energy-response technologies (for checking and monitoring underground facilities). Despite the ongoing efforts to reliably detect and identify the condition of buried pipes at home and abroad, very little has been accomplished when it comes to developing technologies for preventing ground subsidence. Therefore, developing new and innovative technologies to (1) inspect and explore water pipes, sewage pipes, and ducts, and (2) to prevent ground subsidence (which has recently become a major threat) in urban areas is crucial. To this end, this study aims to conduct an in-depth analysis on the measurement and exploration criteria and on technical specifications, prior to developing measurement and exploration technologies (as preventive measures against ground subsidence due to damage to water and sewage pipelines). Based on these, the applicability, efficiency, and feasibility of the technologies will be evaluated, and optimal technical specifications will be suggested.
