【摘要】 通过安全评价模式、基于桥梁实时监测的抵抗内力图和实时内力图的获取、应用实践等几个方面的阐述,将桥梁设计中使用的内力包络验算方法应用于桥梁远程健康监测系统,提出了一种基于内力包络理论的安全评价方法。与现有方法相比,该方法解决了测点有限、不能反映未测位置及桥梁整体状态的问题,具有更直观、客观的优点,并能较好地克服环境与运营条件的影响,具有良好的应用前景。更多还原

【Abstract】 The safety evaluation model,the resistant internal force diagram and real-time internal force diagram based on the real-time monitoring of a bridge as well as the application are expounded.The internal force envelope method in bridge design is applied to the remote monitoring of bridge health,and a kind of safety evaluation method based on internal force envelope theory is proposed.Comparing with the current method,this method solves the problems that the measuring points are limited and can’t reflect the state of unmeasured location and the overall bridge.Therefore,this method is advantageous to be more intuitive and more objective,at the same time,it does better in overcoming environmental and operational conditions and has a promising application potential.更多还原
