Cut and Cover Tunnels • For depths of about 10 m to 12 m, cut-and-cover is usually more economical and more practical than mined or bored tunnelling. • The cut-and-cover tunnel is usually designed as a rigid frame box structure. • In urban areas, due to the limited available space, the tunnel is usually constructed within a neat excavation line using braced or tied back excavation supporting walls.
