桥梁风险贯穿于桥梁建设运营的全过程。本文在分析了大跨度桥梁工程项目风险构成的基础上将模糊数学方法与层次分析法相结合,建立了模糊层次综合评估模型,并以实例通过计算验证了这种风险评估方法的有效性和实用性。
Bridge risks run through the bridge construction and operation of the entire process. Based on the analysis of the risk composition of the long-span bridge project, this paper combines the fuzzy mathematics method and the analytic hierarchy process to establish the fuzzy hierarchy comprehensive evaluation model, and validates the validity and practicability of the risk assessment method by examples .
