摘要
针对目前桥梁养护评估体系难以量化的现状,结合当前风险分析的最新进展,从适用于工程养护实际的角度出发,结合某钢筋混凝土梁实例工程介绍了基于风险分析的桥梁养护方法。通过分析风险因素,评估失效的钢筋混凝土梁的风险值,将养护后风险减少量和养护成本作为评价指标,通过效益-成本分析确定钢筋混凝土梁的最优养护方案。基于风险分析的养护方法为桥梁养护的量化分析和最优养护方案的确定提供了便利。
Aiming at the present situation of hard to quantize the maintenance estimation system of bridge,and combined with the latest progress of risk analysis,the article introduces the bridge maintenance method based on risk analysis by an engineering case of steel reinforced concrete beam from the angle of engineering maintenance practice.According to the analyzed rick factors,the article estimates the risk value of steel reinforced concrete beam out of operation,takes the risk reduction and maintenance cost after maintenance as the estimation index.The benefit cost analysis can define the optimized maintenance scheme of steel reinforced concrete beam.The maintenance method based on risk analysis can be referenced for the quantization analysis of bridge maintenance and the determination of the optimized maintenance scheme.
