Of the Korean military's 3,959 ammunition depots, 1,007 - more than 25% - violate safety requirements for distance and equipment. There is a risk of explosion in old depots that are vulnerable to various interior and exterior accidents. This paper examines 10 scenarios, with varying values for ammunition amount and safety distance. The study calculated the overpressure that can be applied to risk-exposure objects, based on the safety distance; expected damage was predicted using constructed spatial information from 3D explosion simulations. The simulations confirmed that explosion overpressure increased the most when the safety distance violation rate increased from 80% to 90%. It also confirmed that secondary damage such as fire and explosion can cause casualties and property damage when the violation rate is 60% or higher. The results show that building collapse becomes a risk with a violation rate of 70% or higher. We conclude that taking ammunition depot safety distance violation into account when planning military facilities and their land utilization could better protect life and property.

탄약고 지하 및 주변에 시공된 지하구조물의 안정성 평가의 필요성은 도심지 및 사회기반시설의 확장으로 대두되었다. 그러나 지하구조물에 대한 우발적인 폭발의 영향에 대한 연구는 미진하다. 본 연구에서는 지하구조물의 안정성평가를 위한 방법을 제시하고 사례연구를 통해 적용성을 확인하였다. AUTODYN과 SPACECLAIM을 이용하여 구조체 및 지반모델링을 실시하였으며, 폭발효과를 모의하여 지반의 진동속도를 측정하였다. 사례연구의 결과에 따르면, 70m 지하에 설치된 지하구조물은 모의된 폭발 효과로부터의 영향이 거의 없는 것으로 판단된다. 본 연구에서 활용된 안정성평가방법은 지하형 탄약고 설계에 사용되거나, 혹은 주기적인 진동으로부터 영향하에 있는 지하구조물의 안정성을 평가하는데 활용될 수 있을 것이다.

The Army, Navy, and Air Force are currently making various efforts to apply defense IoT technology by reflecting the characteristics of each military. However, there are concerns that comprehensive collection, management, and analysis may be limited because each military has no overlapping system or guaranteed interoperability of data, and there are inefficient aspects in terms of using and investing a limited defense budget. In this study, evaluation items and priorities for pilot projects were selected by applying Delphi technique and AHP method to determine which projects are preferentially effective when commonly applied in terms of Army, Navy, and Air force. As a result of the analysis, the project basis and driving force, project feasibility, performance and ripple effect, redundancy and connection were identified in the order of IoT-based small detachment units and unmanned base construction, intelligent smart unit, smart ground ammunition depot, and smart training management system. According to the comprehensive results reflecting the weights of each evaluation item, the fact that small detachment units and unmanned base construction project are recognized as the first project to be applied to the Army, Navy, and Air Force is a valid approach to be effective while each military is burdened with personnel management because of the reduction of manpower. Through the research results, it is expected that the direction of application to the policy of the defense IoT project can be confirmed in terms of efficient use of limited budgets.
