Abstract
In this paper, The construction disturbance effect of subway tunnel on the cable tunnel of various cross-sectional sizes under various spacing is studied using numerical simulation. The two common working conditions are orthogonally undercrossing and obliquely underpassing cable tunnels under subway undercover tunnel. The main conclusions are: (1) The settlement and tensile stress value of the existing cable tunnel generated by the orthogonally undercrossing is higher than that of the obliquely underpassing; (2) The larger the cross-sectional size of the existing cable tunnel, the higher its structural longitudinal stress and the lower the safety.
