Sustainable Anti-Tank Obstacle System Applying Civil–Military Cooperation in Highly Urbanized Areas

Abstract

Decreasing the use of concrete in construction projects is an important factor in sustainability awareness and green planning. In the past, the military installed and managed concrete block-shaped obstacles called “rock drops” on major roads in order to hinder enemy movement. As the cities surrounding Seoul are developing, traffic volumes are increasing, and traffic networks are expanding, such types of obstacles are becoming obsolete and need to be replaced by a new eco-friendly, urban-friendly alternative. This study proposes a new sustainable anti-tank obstacle and demonstrates its performance through a finite element analysis. In addition, this study analyzes the effect of the proposed obstacle as a civil–military cooperation policy with respect to sustainability by comparing the CO2 emissions between the original and the proposed ones. Once one rock drop obstacle made of massive concrete blocks is replaced, CO2 emissions can be reduced by as much as 99.2%. If 100 rock drop obstacles distributed in the surrounding areas of Seoul are replaced, then 347,581 tons of CO2 emissions would be reduced. This corresponds to total cost savings of USD 17,379,050 based on the Korean carbon transaction price of USD 50/ton-CO2.
