Summary: | During road construction, minimizing haul and return distances as well as keeping a balance between cut and fill quantities are two of the key tasks for earthmoving operation planning. The result of the earthwork planning has a significant impact on the construction cost and duration. Although there have been research efforts regarding optimized earthwork planning using linear programming, the current practice of selecting earthwork planning methods typically depends on a field manager's intuitive and/or experimental knowledge. Furthermore, there is no system considering earthwork influential field factors including the transportation distance, the earthwork quantity, and the recycling ratio of earth volume. Therefore, this research focuses on the development of such a model for planning the optimized earthwork to increase the efficiency of a road construction. The proposed model is developed based upon the transportation problem method which is a part of Linear Programming. The application result of optimization model on a case study shows that the duration and cost for earthwork ha sbeen reduced approximately 19% and 11% respectively 도로공사 토공사 작업현장에서 수행되는 운반계획의 주요 목적은 절토량과 성토량 간의 균형을 맞추는 것과 운반비용, 운반거리를 최소화 하는 것이다. 토공사의 합리적인 운반계획은 공사비 및 공사기간에 직접적인 영향을 미치나, 기존의 토공사 운반계획은 현장관리자의 경험적 지식을 기반으로 토공 운반계획을 수립하는 실정이다. 이에 본 연구에서는 도로공사 토공사 작업현장의 토공물량 운반계획의 효율성 향상을 위해 활용할 수 있는 최적화 모델 개발 하였으며, 사례구간을 통해 본 연구를 적용시킨 결과 공사기간은 약 19%, 공사비는 약 11% 감소시킨 것으로 확인되었다. |
