Solid-fluid-gas coupling prediction of harmful gas eruption in shield tunneling
Tunnelling and Underground Space Technology(2018)
摘要
•Solid-fluid-gas three-phase coupling in FLAC3D was implemented by the Fish language.•A good prediction of harmful gas eruption was done by the numerical modeling.•Some safety standards for the tunneling in the harmful gas strata were put forward.•An automatic monitoring system was designed for the shield tunneling construction.
