TBM General Information

• The excavation depth in Line 1 starts from 11 m and reaches a maximum of 36 m depth at the segment between (1B1-1B2).

• Design life of TBM Bored tunnel is 100 years.

• Design fire resistance is 3 hours.

Geotechnical Design Consideration

• In almost half of the route of Line 1 competent limestone with limited weathering and without groundwater table is expected.

• From station “1F2” to “1F4” in line 1, TBM cross a silty clayey sand layer.

• Typically settlements over the tunnel (0-10mm).

• Some areas of greater predicted settlement (10-30mm) in the southern section of the Line 1 tunnel, near Station “1F2”.

Geometry of TBM

• The tunnel internal diameter is 9.0m

• This diameter is further increased by 0.2 meter to accommodate TBM construction tolerance as required.

• The proposed TBM final lining is precast segments of 360mm thick.

Soil Excavation Quantity

• In a simple calculation, we can assume the quantity of soil to be excavated.

• Area of tunneling= 77.29 m2

• Tunneling Length= 17.3 km

• Soil Volume= 17300*77.29= 1337117 m3
