The Evaluation Model of the Bridge Approach Design Scheme Based on the Life Cycle Cost Theory

The bridge approach is the important connection of the bridge and the original traffic. It has play a decisive role. The reasonable bridge approach design scheme is the key to ensure the engineering quality of the bridge approach. In recent year, the life cycle cost theory is applied in the construction of the road, the bridge and other infrastructure projects more and more widely. The life cycle cost theory includes the life cycle, the life cycle cost, the character of the life cycle cost, the life cycle cost control, the life cycle cost management etc. Based on the life cycle cost theory, put forward the concept of the life cycle of the bridge approach and the life cycle cost of the bridge approach. By analysing the life cycle and the life cycle cost of the bridge approach, establish the life cycle cost evaluation model of the bridge approach. The model is used to evaluate the design scheme of a bridge approach. The evaluation conclusion is consistent with engineering experience.
