Sinkholes are a significant underground hazard that threatens infrastructure and lives and
sometimes results in fatalities. The annual cost of sinkhole damages exceeds $300 million …

For tunnel buried in water-rich sand stratum, water intrusion into tunnel lining would bring
sand particles into the tunnel and then caused ground subsidence or even cave-in of …

Ground collapse due to soil erosion near pipeline defects involves soil loss and orifice
outflow, which may lead to non-Darcy flow, but it is often ignored in numerical simulations. In …

Most of urban ground collapses and tunnel failures are caused by joint leakage of shield
tunnel lining. This paper conducts a series of model tests and particle flow simulations …

In the past several years, the high frequency of cave-in failures of urban roadways has
posed a serious threat to the safety of traffic, pedestrians, and existing structures and …

This paper revealed the influence of buried structures on the development of underground
cavities with internal erosion from the breakage of sewer pipes, and investigated the spatial …

Sinkholes induced by long-term internal erosion around defective sewer pipes have been
widely reported. There is a need for an efficient method to understand the influence of pipe …

Ground collapse is a common urban geological disaster mainly triggered by the leakage of
underground drainage pipe. To reproduce the process of underground cavity formation and …

Damage or deterioration of water distribution or storm water drain pipeline systems create a
problem of leakage, which has the potential to erode its surrounding soil. This erosion, if not …

Ground subsidence induced by internal erosion around defective sewer pipes commonly
occurs in urban areas of many cities over the world, which has caused substantial …
