Centrifuge modeling of tunneling-induced ground surface settlement in sand
Underground Space (China), 2019 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 the three-dimensional ground surface settlement, considering different intersection angles and ...

Ground settlement induced by NATM tunneling and surface loads in Shiraz metro station
Scientific ReportsUrban tunneling, especially in the construction of shallow metro stations, can lead to significant ground movements that may affect the safety and integrity of nearby surface structures. This research explores how surface settlements develop during NATM-based tunnel excavation, focusing particularly on the role of ground surface loads from traffic and ...

Surface settlement prediction for EPB shield tunneling in sandy ground
KSCE Journal of Civil Engineering, 2017 Ground volume loss induced by shield tunnel construction is the major factor leading to ground settlement and deformation. The general equations predicting surface settlement based on ground volume loss involve a settlement trough width coefficient (parameter i) which in previous models was set as a constant in both the transverse and longitudinal ...

Influence of large diameter deep buried pipe jacking construction on surface settlement
地质科技通报, 2022 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,

Control settlement of recharge in ultra-deep excavations under partial block effect of aquifer
Yantu gongcheng xuebao, 2021 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.
