Ground settlement and tunnel response due to twin-curved shield tunnelling in soft ground with small clear distance

Journal of Rock Mechanics and Geotechnical Engineering
Twin curved tunnels are often encountered in shield tunnelling, where significant complexities in densely exploited underground space are observed. In this study, the ground settlement and tunnel deformation due to twin-curved shield tunnelling in soft ...

Bayesian updating for ground surface settlements of shield tunneling

Frontiers in Earth Science, 2023
Accurate prediction of ground surface settlements induced by shield construction is of great significance for ensuring the safety of shield construction. This paper proposes a ground surface settlement prediction method for shield tunneling based on Bayesian updating.

Experimental Research on the Settlement Feature of Two Ground Deformation Modes Induced by Tunnelling

Mathematics, 2023
Two ground deformation modes, i.e., the arching mode and collapsing mode, may be caused by tunnel excavation. However, the development of the ground deformation corresponding to the two modes is unclear.

Prediction model and application of three-dimensional ground surface settlement induced by tunnel excavation considering time effect

矿业科学学报, 2019
It is difficult to consider the change of settlement along with time by using stochastic medium theory in the settlement prediction process in subway construction. A new settlement-time model is proposed.

Deformation characteristics of ground with voids induced by shallow metro tunnelling

Yantu gongcheng xuebao, 2019
The existence of the ground voids makes the ground conditions around the tunnel more complex, which may increase the ground surface settlement and even induce collapse during shallow metro tunneling.
