An Experimental Study on the Reduction Method of Earth Pressure Acting on the Cut-and-Cover Tunnel Lining

[ 초 록 ] 

Cut and Cover Method is generally used in shallow tunnels and tunnel entrances with thin soil cover, In this type of consotruction, backfilling is considered to be the most important process.

In this process even though the backfill material is thoroughly compacted, compaction and self-weight due to vehicular vibration and pressure exerted by the soil cause the backfill material to undergo self-compression which leads to settlement.

The settlement of the backfill material subjects the tunnel lining under excessive earth pressure which cause cracking and deformation.

In the model test performed installation of geotextile on the sides and top of the tunnel was able to reduce the earth pressure acting on the tunnel lining.
