The prestressed anchor cable is widely used in the projects of soft rock, soil slope reinforcement and open-excavated tunnel support system. Depending on the cable support system project for large span of Shuangliu Airport Tunnel in Chengdu-Mianyang-Leshan Passenger Dedicated Railway, the forcing characteristics and working principle of dispersion type prestressed anchor cable in the support system for deep foundation pit of open-excavated tunnel is analyzed; and the technical essentials and process for construction of new cable is analyzed as well.
