摘　　要：主要针对钢桥有效的寿命周期成本(LCC)的优化设计中实际产生的LCC进行了简要的描述和规定。一般钢桥优化设计的LCC模型中,包括钢结构桥梁的初始成本和直接/间接的修复成本,维修/更换成本,材料损坏或者疲劳损失,道路使用者的成本,间接的经济损失。因此,论文着重介绍一般配方的模型和适合实际操作的钢桥有效的LCC系统模型设计。This paper address a practical life-cycle cost （LCC） formulation and procedure for the LCC-effective optimum design of steel bridges. A general LCC model for optimum design of steel bridges consists of those of initial cost and direct/indirect rehabilitation costs of a steel bridge, including repair/replacement costs, loss of contents or fatality and injury losses, road user costs, and indirect losses.Thus, this paper focuses on the presentation of a general formulation of LCC models and LCC-effeetive design system models for steel bridges suitable for practical implementation.

关 键 词：寿命周期成本 钢桥 优化设计 可靠性
