基于随机预测的青岛海湾大桥桥墩防腐维修措施成本优化

以氯离子渗透理论和全寿命周期成本理论为基础,采用蒙特卡洛数值模拟方法,对海工混凝土桥墩的维护维修措施进行了对比分析,以期在保证安全性、适用性的前提下达到降低维修维护成本的目的.首先对青岛海湾大桥桥墩使用寿命进行随机预测；其次,对单项维护维修措施进行随机模拟；第三,对各种措施综合使用方案进行随机模拟；最后,计算各种综合方...

Cost Optimization of Corrosion Maintenance Measures for Qingdao Bay Bridge Piers Based on Stochastic Prediction

According to the theories of chlorion penetration and life cycle cost analysis,the maintenance and repair measures for concrete piers in marine environment was comparatively analyzed through Monte Carlo simulation to minimize the maintenance cost under the premise of ensuring the safety and applicability.First,stochastic prediction for the service life of Qingdao Bay Bridge piers was carried out.Second,the stochastic simulation for single maintenance or repair measure was given.Third,the stochastic simulati...
