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.
