What are the causes of urban road collapse?

[OMichael]

There are many reasons for road collapse, which may be due to continuous heavy rain or excessive traffic, but ultimately it is due to excessive surface load, such as over-concentration of population and dense tall buildings. Continuous heavy rain: The reason why continuous heavy rain can cause collapse is that long-term soaking by rainwater can loosen the roadbed, leading to local collapse, just like the heavy rain in Henan, which will definitely cause road collapse accidents. Preventing road collapse: Of course, the relevant departments have also made great efforts to prevent road collapse, such as using radar to detect road cavities, inspecting and repairing old pipelines, and monitoring road settlement and pipeline deformation, which are also means of prevention.
