Ground subsidence due to the backfill pressure in tunnel boring machine [PDF]
Proceedings of the International Association of Hydrological Sciences, 2020 In shield tunnel boring machine constructions, backfill pressure affects surface settlement and the stability of other underground structures nearby. Therefore, it is essential to pre-calculate backfill pressure in the design stage.

Prediction of Ground Settlements Associated with Shield Tunnelling
Soils and Foundations, 1978 There is much uncertainty to estimate the ground settlement associated with shield tunnelling due to the complicatedly interacted conditions between tunnelling methods and soil characteristics. Accordingly, if the shape of the ground settlement could be quantitatively predicted, it would be very effective for the assessment of its influence on the ...
