内容简介

　　可 靠 性 分 析　　——混凝土桥的结构处理工具　　钢筋混凝土桥结构对多种恶化机制敏感，包括碱趋于和缓行动和氯化物进入。 实际的研究已经被与这些机制和其他问题联系起来承担。 这一直特别在那些案件在过去的大约20年，那些目标是鉴定引起，结果并且发展补救策略。 这已经改进加强的混凝土的理解长期性能并且导致技术的发展增加恶化抵抗。 　　目前，在一个问题已经被鉴定之后，最共同的方法是行动，被称为重新活跃的维修。 这不可能以前最经济解决办法，在许多场合，维修比比预防处理方法昂贵。 不过，在恶化是明显的之前，拥有人经常不愿意为预防处理方法支付。 处理方法的尽快应用归根结底可能不是这个最佳的解决办法。 综合恶化和性能预测模型化对很重要支持积极计划和检查，试验与维修。 这作为年龄和理由给提供资金的维护变得越来越批判性的基础设施变得越来越重要。　　英文翻译　　Reliability analysis :　　a structures management tool for concrete bridges　　Reinforced concrete structures are susceptible to a variety of deterioration mechanisms, including alkali-thaw action and chloride ingress. Substantial research has been undertaken in relation to these mechanisms and other problems. This has particularly been the case over the last 20 years or so, where the objective has been to identify causes, consequences and develop remediation strategies. This has improved understanding of long-term behaviour of reinforced concrete and resulted in the development of techniques to increase deterioration resistance.　　At present, the most common approach is to act after a problem has been identified, known as re-active maintenance. This may not be the most economic solution since, in many cases, maintenance is more costly than preventative treatments. However, owners are often reluctant to pay for preventative treatments before deterioration is apparent. Early application of treatments may not be the optimal solution in the long run. Integrated deterioration and performance prediction modeling is essential to pro-actively plan and prioritise inspection, testing and maintenance. This becomes increasingly important as infrastructure ages and justification for maintenance funding becomes increasingly critical.
