When metro shield passes through existing operating lines, it is necessary to carry out automatic monitoring of existing lines. Taking Changsha Metro Line 4 shield tunnelling through existing Metro Line 2 as an example, this paper carries out automatic deformation monitoring of existing Metro and judges the influence of shield tunnelling on existing Metro. According to the actual situation of the field, a whole set of automatic monitoring system is designed, and the detailed implementation plan is worked out. Finally, the deformation data are analysed, and the characteristics of the whole system are summarized.
