Centrifuge modeling of tunneling-induced ground surface settlement in sand
Stress changes in the soil induced by tunnel excavation may cause excessive ground settlement. However, high-quality experimental data on ground settlement due to tunnel excavation are limited. In this study, centrifuge tests are conducted to investigate

Influence of large diameter deep buried pipe jacking construction on surface settlement
Pipe jacking construction is widely used in urban construction due to non-excavation or less excavation, but the surface settlement caused by pipe jacking construction cannot be ignored. Relying on a pipe jacking project of a power tunnel in Foshan City,

Numerical investigation of ground surface settlement due to circular tunnelling influenced by variations of geometric characteristics of tunnel and mechanical properties of saturated soil and its prediction in the artificial neural network [PDF]
The settlement of the ground surface due to tunneling are considered as tunnel instability factors, as well as the displacement of the crown of the tunnel.

Control settlement of recharge in ultra-deep excavations under partial block effect of aquifer
In coastal cities in China, taking Tianjin for an example, the pressure aquifer is rather thick and buried deep. Cutting off all the aquifer will lead to high construction cost.
