The invention relates to the technical field of tunnel construction monitoring, in particular to a ground subsidence monitoring device for tunnel construction, which comprises a buried seat, a buried pipe mounted on the buried seat, a plurality of subsidence frame mechanisms movably connected to the buried pipe, GPS positioners mounted on the plurality of subsidence frame mechanisms, a plurality of limiting rings fixedly connected to the buried pipe, and a plurality of ground subsidence monitoring devices movably connected to the plurality of limiting rings. The multiple limiting rings and the multiple sedimentation frame mechanisms are arranged in a staggered mode at intervals, and one limiting ring is arranged below each sedimentation frame mechanism in a matched mode. When the ground subsidence occurs, not only can the subsidence information of the ground surface layer be judged, but also the subsidence compression information of multiple types of soil layers can be monitored and judged, the relative chang
