Zusammenfassung:PROBLEM TO BE SOLVED: To save labor for works by shortening a construction period and reducing construction costs by decreasing the number of times of driving and pulling in tunnel lining works. SOLUTION: Prior to the tunnel excavation, in a tunnel lining method for building at least a pair of vertical lining slabs 3, 3 and an upper floor lining slab 10 to be connected to the upper portion of these vertical lining slabs 3, 3 for dividing the tunnel section inside the ground, a floor slab 7 having a width corresponding to the span at least between the vertical lining slab 3, 3 is used as the lining material for the upper floor lining slab 10.
