Abstract Inspection process provides beneficial information to assess the current condition of the bridge deck, which is an essential factor in identifying the most appropriate and timely maintenance strategy. Practically, there are a huge number of bridges that need frequent inspection, which makes planning for this process crucial. In this regard, a bridge deck inspection planning (BDIP) model was developed to manage the inspection process of the concrete bridge deck. This model integrates agent-based and discrete event simulation approaches to mimic the sub-processes involved in the inspection using non-destructive technologies. This paper discusses the details and the adopted procedures to build this model starting from real system analysis to model verification, implementation, and validation. Verification and validation of the model demonstrate its ability to accurately estimate inspection duration and cost. The developed model can assist bridge authorities and contractors in planning this process, measure the traffic disorder due to inspection activities, and compare different scenarios for conducting inspection.

基于仿真的混凝土桥面板无损检测规划

摘要 检查过程为评估桥面板的当前状况提供了有益的信息,这是确定最合适和及时的维护策略的重要因素。实际上,有大量桥梁需要经常检查,这使得对这一过程进行规划至关重要。在这方面,开发了桥面检查计划 (BDIP) 模型来管理混凝土桥面的检查过程。该模型集成了基于代理和离散事件模拟方法,以使用无损技术模拟检测中涉及的子过程。本文讨论了从实际系统分析到模型验证、实现和验证的构建该模型的细节和采用的程序。该模型的验证和验证表明其能够准确估计检查持续时间和成本。开发的模型可以帮助桥梁当局和承包商规划这个过程,测量由于检查活动造成的交通混乱,并比较不同的检查场景。
