摘要
水闸工程中为了方便通行,有时会将工作桥兼做交通桥,在水闸工程使用期间,这种桥梁不同于一般的工作桥,由于运行维护不足和使用年限问题,这类桥存在一定的安全隐患,如果处理不及时易发生安全事故。以某水闸中工作桥兼做交通桥的工程为例,给出其安全评价的方法,并给出如何计算分析其在不同工况下的内力和构件强度,分析了该工作桥的安全现状,为类似工程提供借鉴和参考。
Sluice operating bridges sometimes are used as traffic bridge for convenient traffic; however, this kind of bridge is different from ordinary bridges.Due to the lack of maintenance and safety operating years, safety risks may exist, and safety accident may occur if the risks are not well handled in time.Based on a bridge which is used for both traffic and operation purposes, a method for safety evaluation of this type of project is introduced, also the method provides approaches to calculate the inner force and strength of the structure in various working conditions; in addition, the safety state of the bridge is analyzed, which is a reference for similar projects.
