Based on investigation of landform and topographic features, engineering, hydrogeology, the land subsidence features along the planed Ningbo rail traffic line are analyzed by using the dynamic propagation results of subsidence funnel, statistical results of every soil layer deformation and cumulative settlement in the subsidence center. The existing problems of the regional land subsidence monitoring in Ningbo are also analyzed. Furthermore, land subsidence monitoring network layout program along the planed area in Ningbo rail traffic are proposed. The land subsidence bedrock mark, land subsidence classification mark, reference points, testing hole for pore water pressure and groundwater monitoring well are included in the monitoring network.  Finally, land subsidence monitoring and pre-warning solutions are discussed.
