桥梁设计与建设步伐发展很快,但是在发展的过程中出现了许多弊端与不足。桥梁安全性与耐久性不足会产生巨额的经济损失、严重的工程事故、恶劣的环境社会影响。桥梁耐久性问题在设计中存在的主要不足体现在设计规范的先天不足、设计中具体细节注意不够、设计人员学习、更新知识不够等方面。针对以上不足采用的应对措施主要是健全规范、更新设计理念、创新设计方法。主要从桥梁设计耐久性不足有主要危害、桥梁设计中存在的问题、应对措施等主面进行论述。 The pace of bridge design and construction has developed rapidly, but many shortcomings and deficiencies have emerged in the process of development. Lack of safety and durability of the bridge will result in huge economic losses, serious engineering accidents and harsh environmental and social impacts. Bridge durability issues in the design of the main shortcomings are reflected in the inherent design deficiencies in the design details of the design is not enough attention, designers learn to update knowledge is not enough and so on. The response to the above shortcomings are mainly to improve the norms, update the design concept, innovative design methods. Mainly from the lack of durability of the bridge design, there are major hazards, the bridge design problems, countermeasures such as the main surface are discussed.
