- •
A soil–fluid coupled model was conducted to simulate cross passage behaviour.
- •
Cross passage affects little on the long-term surface ground settlement.
- •
Cross passage tunnel further squats as soil consolidates after construction.
- •
A “table” load analogy was proposed to illustrate the 3D long-term soil arching.
- •
The tunnel segment adjacent to the opening at the axis level is critical.
