Sandy aquifer collapse mechanism and accident treatment of the Qingdao metro tunnel
Frontiers in Earth Science, 2023 The tunnel collapse occurred during the construction of the Qingdao Metro Line Ⅰ, resulting in a pit measuring approximately 10 m in diameter and 7 m in depth on the ground surface.

Numerical modeling of tunneling induced ground deformation and its control [PDF]
International Journal of Mining and Geo-Engineering, 2016 Tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. The predication of ground movement during the tunnelling and optimum support pressure could be based on ...

Surface settlement induced by horizontal directional drilling
Underground Space, 2023 Horizontal directional drilling (HDD) is a widely used trenchless method for underground utility connections. The associated ground settlement triggered by HDD depends on the size, types, and surface texture of pipe, diameter of borehole, and soil conditions.
