由于共处一地和空间邻近，日益恶化的水利基础设施 (WI) 和交通基础设施 (TI) 具有复杂的相互依赖性，包括道路到管道的物理依赖，以及管道到道路的运营依赖。一方面，交通负荷不仅是道路物理退化的主导因素，而且也可能是同一地点道路下的管道因极端传播应力而突然失效的重要影响因素。另一方面，水管破损和维修也会造成交通堵塞、车道封闭、路面重新铺设等，影响道路使用成本和道路养护成本。现有的维护工作大多主要是单独考虑WI和TI，而忽略了它们复杂的相互依赖关系。本研究提出了一个联合主动维护规划框架，针对退化不确定性下的同地道路和管道，明确考虑到它们的物理和运营依赖性。特别是，管道同时考虑了交通引起的突然失效和腐蚀引起的逐渐失效的竞争失效模式，以捕获物理依赖性。还为道路制定了管道维护中断时的道路维护成本和道路使用者成本，以捕获运营依赖性。进一步提供了一个案例研究，以综合评估所提出的联合维护规划策略相对于几个现有基准策略的性能，并证明所提出的工作的成本节约效益。相互依赖性对拟议维护计划决策的影响也进行了彻底调查。
Due to co-location and spatial proximity, deteriorating water infrastructure (WI) and transportation infrastructure (TI) have complex interdependencies, including both physical dependency from road to pipe, and operational dependency from pipe to road. On one hand, traffic load is not only a dominant factor for the physical degradation of road but may also be an important contributing factor to the sudden failure of the pipe underneath the co-located road due to the extreme propagated stress. On the other hand, the water pipe breaks and repairs will also cause traffic blockage, lane closure, and repaving of road surface, which influence both road user costs and road maintenance costs. Most of the existing maintenance work mainly considered WI and TI separately but neglected their complex interdependencies. This study proposes a joint proactive maintenance planning framework for the co-located road and pipe under their degradation uncertainties by explicitly taking into account both their physical and operational dependencies. In particular, the competing failure modes of both the traffic-induced sudden failure and the corrosion-induced gradual failure are simultaneously considered for the pipe to capture the physical dependency. Road maintenance costs and road user costs in the presence of pipe maintenance disruption are also formulated for the road to capture the operational dependency. A case study is further provided to comprehensively evaluate the performance of the proposed joint maintenance planning strategy over several existing benchmark strategies and demonstrate the cost-saving benefit of the proposed work. The impacts of interdependencies on the proposed maintenance planning decisions are also thoroughly investigated.
