摘要
建国以来,我国兴建了大量的公路桥梁。由于长期服役的磨损及超载破坏等原因,这些已建桥梁部分存在可靠性问题,需对其进行可靠性评估。而在目前存在的多种可靠性评估的理论与方法中选用哪种方法更切实可行显得尤为重要。本文对桥梁评估的各种方法进行了综述,并对各种可靠性评估常用方法优缺点进行了分析阐述,以供科研人员与工程实践人员参考。
Since1949,a larger number of highways and bridges have been built in China.Due to the wear of long-term service and overload damage and other reasons,reliability problems arise in some of these built-bridges,which lead to assessment of bridge＇s reliability essentially.Therefore,it is very important to select a feasibility method from existing variety of reliability assessment theories and methods.In this paper,many kinds of reliability assessment methods are summarized,advantages and disadvantages of usual methods are expounded as well,which can be used for scientific research personnel and practical engineers as a reference.
