Abstract:

This paper discusses the methods of utilizing the double-intersecting conducting wires in long and large cross section tunnels to test the tunnel's internal control network. This method is developed to strengthen the structural stability of the net-shaped conductingwires inside the tunnel,and to improve the boring precision across the tunnel.

Key words: intersecting conducting wires, establishment of a tunnel's internal control network, precision analysis
