| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 87 === Essentially every large civil or building project involves earthmoving operation. It is not atypical for a highway project, for instance, to have to move more than 1,000,000-m3 earth between locations. Several mega projects, such as the second freeway, the high-speed railroad, and the rapid transit railways are currently underway in Taiwan, which all involve the movement of a huge amount of earth. Substantial amount of project cost can be saved with a better planning of the operation.
The earthmoving operation mainly involves the interaction of excavators and hauling trucks, while its efficiency also affected by factors such as the property of the earth, the moving distance, the road conditions, and so on. This research employs computer process simulation technique for the planning and analysis of earthmoving operation especially with the consideration of “similar resources.” Combinations of excavators and trucks with different capacities, performance efficiencies, and other attributes (similar resources) are tested out on a computer model (STROBOSCOPE) to study the significance of considering the “similar resources” in the planning and analysis of the operation. The objectives are to improve the productivity and the cost effectiveness of the earthmoving operation with optimized combinations (numbers and sizes) of excavators and hauling trucks employed in the operation.
