摘要
《钢筋混凝土桥梁剩余寿命评估方法研究》项目针对桥梁剩余寿命突出问题,从7个专题开展系统深入的研究,完善了基于多重因素的混凝土碳化深度预测模型和钢筋碳化腐蚀速率模型,提出了计算锈蚀钢筋混凝土梁、偏心受压柱和拱肋承载力的新方法,构建了基于时变可靠度的钢筋混凝土桥梁剩余寿命评估方法,提出了钢筋混凝土拱结构时变可靠度计算等方法。项目研究成果具有显著的创新性,良好的社会经济效益和推广应用前景。
The study on the remaining life of reinforced concrete bridge perform the research from seven angels.It completes the concrete carbonization prediction model and carbonization corrosion speed model,and proposes the new method to calculate the corro-sion of reinforced concrete pile,eccentric pile and arch bearing capacity.It also constructs the evaluation method that based on time-changing reliability and provides calculation method for it.The research result shows high creativity,good social and economic profit-ability and bright future.
