城市地区越来越多地受到地下热岛的影响：地下气候变化导致环境，公共卫生和交通问题。土壤、岩石和建筑材料会在温度变化的影响下变形，过度变形会影响土木基础设施的性能。在这里，我探讨了地下热岛引起的地面变形是否会影响民用基础设施。芝加哥卢普区作为一个案例研究。通过温度传感器网络收集的数据提供信息的三维计算机模型用于表征地下气候变化引起的地面温度变化，变形和位移。这些变形和位移是显著的，并且根据具体情况，可能与土木结构的操作要求不相容。因此，地下气候变化对民用基础设施的影响应考虑在未来的城市规划策略，以避免可能的结构损坏和故障。总的来说，这项工作表明，地下气候变化可能对芝加哥环路和世界其他城市地区的民用基础设施造成无声的危害，但也是重新利用或最大限度地减少地下废热的机会。
Urban areas increasingly suffer from subsurface heat islands: an underground climate change responsible for environmental, public health, and transportation issues. Soils, rocks, and construction materials deform under the influence of temperature variations and excessive deformations can affect the performance of civil infrastructure. Here I explore if ground deformations caused by subsurface heat islands might affect civil infrastructure. The Chicago Loop district is used as a case study. A 3-D computer model informed by data collected via a network of temperature sensors is used to characterize the ground temperature variations, deformations, and displacements caused by underground climate change. These deformations and displacements are significant and, on a case-by-case basis, may be incompatible with the operational requirements of civil structures. Therefore, the impact of underground climate change on civil infrastructure should be considered in future urban planning strategies to avoid possible structural damage and malfunction. Overall, this work suggests that underground climate change can represent a silent hazard for civil infrastructure in the Chicago Loop and other urban areas worldwide, but also an opportunity to reutilize or minimize waste heat in the ground.
