Abstract: They were manually caved in argillaceous siltstone at shallow depths more than 2000 years ago.To address this question, this paper proposes a hypothesis that the argillaceous siltstone has the abilityThe results have shown that the argillaceous siltstone is in a state of weak alkalinity and the rainTherefore, when it is immersed in weak acid water for some time, the argillaceous siltstone would be

Clogging of slurry-shield tunnel-boring machine drives in sedimentary soft rock: A case study

Frontiers of Structural and Civil Engineering doi: 10.1007/s11709-023-0984-8

Abstract: clogging of a slurry-shield tunnel-boring machine (TBM) experienced during tunnel operations in clay-rich argillaceousThe potential for clogging during tunnel operations in argillaceous siltstone was estimated using an
